Pro Material Combiner, Combine Materials Quick and easy with just 2 clicks!

Hey Guys,

ProMaterial Combiner And ProMaterial Combiner++ are editor extensions that just by selecting an object
and clicking on combine it will compress all your materials to just one.

This package will remap and combine automatically each of your UV maps on your
meshes to a single atlas.

With this you will get rid of the overhead of having several materials on each of your
meshes and also reduce the number of draw calls each of your renderers consume.

Have specific / custom shaders?, dont worry, the tool will automatically
recognize any custom shader and work with it.

Both tools do exactly the same, the differences are that ProMaterialCombiner++ includes:
- Source code.
- Reuse textures: Makes atlas smaller.
- Batch mode: Combine several objects materials quickly.

UNITY 5 supported.

NOTES:
- Easy, Just select your object and click combine.
- No scripting required.
- Meshes automatically set up and adjusted.
- Support for any custom shader (detected automatically).
- Full lightmapping support.
- Your source assets will not be touched.
- Works with colored and textured materials.
- Supports tiled materials.
- Generate prefabs from the combined object.
- Supports skinned mesh renderers.
- Malformed UVs on colored-only materials are organized automatically

NOTE: In order to combine materials all shaders have to be the same type.

What is the difference with your other asset Pro Draw Call Optimizer?

 

Hey @angel_m

ProMaterialCombiner combines materials per game object and that's pretty much it, ProDrawCall combines materials per game object plus materials on all your game objects.

thats pretty much, that's why ProMaterial's price is lesser.

if you have ProDrawCallOptimizer you can do what ProMaterialCombiner does.

ProMaterialCombiner is useful when you just need to combine materials in your game objects .

 

Hi @jmunozar, does this asset support combining material colors to vertex colors? It seems it only outputs textures with the colors as blocks.

 

hey @tonic ,

Unfortunately no, what the tool does is that given the shader you are using if the shader doesn't have a texture then it takes the UVs of the mesh and centers (0.5f, 0.5f) it to the colored-generated texture.

The tool doesn't generate a new shader with the colors (which is what it would needed to be done if you wanted to have vertex colors), instead it uses the shader the game object has and creates a texture from the colors.

Hope this answers your question

 

Thanks @jmunozar for a good answer. I found another tool which did what I wanted (put colors of multiple materials to vertex colors and single mesh&material).

(Except it was unable to optionally output two separate batches split by opaque and transparent. That is, optionally I'd like to have two output materials when there is both opaque&transparent stuff present... so that's a feature I'm still missing.)

 

ah, could you point me to the tool you found?, I'm curious how it achieves this without changing the shader

 

@jmunozar, it did require changing of vertex shader (and came with several ones for that), sorry for not making that clear. But it also worked with this vertex color version of the standard shader.

 

Ah I see, still thanks a lot for sharing the link I'm going to check it out

 

Hello!

What if I have a game object with two diferent kind of materials? for example I have 3 diffuse materials and other 4 toon materials in the same game object, can I use this tool to combine the 3 diffuse materials in one and the 4 toon materials in one so the game object will have only two materials? just one diffuse and one toon.

Im very interested in buying this asset, thanks!

 

Hey @Dolzen, if you had one game object with multiple materials. BUT all the same shader, the tool will combine them for you automatically.

Being said that, if you have different type of materials in your game object it will not work unfortunately.

 

thank you!

 

It works with multiple UV? I have a game object with multiple materials all the same shader but the shader use two different textures with two UV one for each texture, it is supported?

Thanks!

 

Hey @dolzen,if the shader is the same and the UVs are in the [0,0-1,1] space then yes, it will merge it into one material =)

 

Is this asset still supported and get upgrades ? I really need asset like this.
Thanks

 

Hey @MoribitoMT,

Yes, if it's still selling it will get upgrades and be supported. The thing is that there's not much to add to this tool now besides stability and support =)

 

Hello,

I am looking into buying the Material Combiner ++, because I need to create one texture atlas for several trees and bushes, the problem that I am finding is that the tree models uv, are using tiling vertically meaning that the leafs are uv are within the [0,0,1,1] but the tree trunks are using [0,0, 1, 1+]. Does your tool allows for me to make horizontal atlas? Say for example an atlas 3072 by 1024? so the tree trunks can tile vertically. In this example the individual texture map would be 1024 x 1024 repeated horizontally.

And I don't want to combine the tree models into 1, so it must work with separate models

Regards,
Carlos

 

Hey @strongbox3d,

Unfortunately I cannot tell you accurately if it will work. This is because the packing algorithm doesn't normally pack your textures in certain order. It starts packing by area size(from bigger to smaller).

So in your case te result will be unexpected and likely to not work. =(

 

Thanks for your quick response. What a shame, because I could really benefice from a texture packer that does that. Unfortunatelly I can't change the uvs of the tree since they were created with the Tree creator inside Unity.

Regards,
Carlos

 

Hello Carlos,

Yes, I can totally understand. But is better to honest so you know where are your spending your money =).

If you have any question, don't hesitate to ask. =)

Juan

 

Thank you Juan.

 

I bought this asset.
I tried combine materials of diffuse shader.
But it failed combine.
Error are as follows.

Hello @akerusoft,

Thats because the number of submerged you have mismatches the number of materials you have.

Could you check the number of submerged are the same number as materials? =).

Let me know if you struggle, I'm here to help ;-)

 

Hello.
I am not good at English.

As in the attached image, I think that there is the same number.
Where can I check the number of submerged?

 

Hello @akerusoft

No worries. Can you send me your mesh to my email so I can check it?

I'll give it a look and get back to you after work

 

Hello @jmunozar ,I am a Chinese.I bought your Pro Material Combiner++ in the morning,It is so good,But I don't know why this happens.Can you help me?

 

Hello @JecksonLiu !,

Sorry for the late reply! I was actually sleeping . The issue you are having there; if you checkout the console; is that you are having UV problems; That means your UVs are outside 0,0-1,1, hence some of your meshes are using textures that are from other meshes in the atlas (neighboor textures). Checkout this video so you can understand what the problem is:

I also made this video to "fix" that issue more or less easy.

If you want to have tiled textures; the best way to do it is by setting the tiling within the material instead from the UVs themselves.

Do let me kow if you have any other question

 

@jmunozar

Can this be used to create atlases shared by more than 1 skinned mesh, or is it per-mesh only? And can the result be edited, or does it produce an .asset file?

Thank you.

 

Hello lod3.

If you create a prefab it generates an asset file. Yes you should be able to share the same material between skinned mesh renderers. Byou will need to duplicate the mesh objects.

Now. If you want your original meshes to have the same Atlas then it will not be possible. As you will need to modify the UVs on those meshes to match the position in the Atlas. For that. Use Prodrawcall optimizer. Which will map different meshes to a same Atlas.

Hope this answers your question

 

Hi @jmunozar

Actually what I'm trying to do is take a skinned mesh that has 2 texture variations (2 materials each), but combine all 4 materials into one atlas since the source mesh is the same. Is this possible?

And it appears the evaluation version of PDC does not support skinned meshes. I tried everything I could think of, but it keeps reporting my skinned meshes as "Not optimizable", even using Legacy Diffuse as instructed. I even tried other skinned meshes as well.

 

Yes

Hello Lod3.

Yes it should work. I just private messaged you with some details ;-)

 

Hey,

So just tried this asset out on one of my models and I'm getting an IndexOutOfRangeException, at this line:


What needs to be done so that the masterMesh.uv will have values?

 

Hello @eedok

That can mean that your mesh has less UVs / more UVs or you are mising a material that the mesh has.

how many materials does the original mesh has? and how many materials are you using in the inspector?

 

@eedok; couple of quick questions. Do the examples that come with the package work?. if you cannot solve the issue, do send me your mesh and I can take a look into it and tell you more precisely what's going on

 

Hello @eedok
Thanks for sending the file that fast . The problem that you are getting is because as your mesh contains more than 65535 vertices, by default unity splits it it in sub meshes and doesnt preserve the indexes of the UVs (corresponding to each mesh), hence you are getting that null ref exception.

The only way to solve this is by either split your mesh from the 3D app or use meshes with less than 65535 vertices. Try that out and if the problem persists do let me know ;-)

 

Hi there!
I'm interested in this asset as before I looked at your other asset: Pro Drawcall Optimizer.
Would like to know the difference between this one and the PDO
Seems this asset can also combine materials from different game objects if I got it right in the description.
So can this one be used to combine multiple speedtree's materials together without meddling their meshes?

 

hello @Harekelas
ProMAterialCombiner works only on single game objects and combine their several materials into just one. if you have ProDrawCallOptimizer there is no need to have this as ProDrawCall already does what this tool does + combines several game objects.

Being said that. for speed trees I'm not sure if it will work due to the vertex coloring property.

Hope it answers your questions

 

Hello!

I'm trying to combine several materials of a single object (they all use common standard shader), but the tool is not allowing it, displaying the message "Different types of standard shader in the object, check textures".





Am I doing something wrong?

Thanks in advance.

 

Hello Fabio.

The standard shader changes depending on the textures you have allocated. All those standard shaders should have textures in the same slots in order to be combinable.

That should fix your problem

 

Hello,

Does this tool creates texture atlas for different independent object without the need to combine the objects? I have several stones, houses, furniture, that I DON'T want to combine into a single mesh, but I want them to use the same material with texture atlases for each type of texture(diffuse, normal, height, specular, etc). Please let me know because I am ready to buy right now if it does this.

Regards,
Carlos

 

Hello @strongbox3d,

The tool you are looking for is Pro Draw Call optimizer.

ProMaterialCombiner will combine one object if it has several materials; Pro Draw Call optimizer will combine several objects into one material.

DO bare in mind that if you use promaterial or prodrawcall and your objects have several materials in one object; in order to combine them they need to have the same type of shader; and in the case is the standard shader, they need to have assigned the same texture slots accross the game objects.

Checkout ProDrawCall optimizer light:
https://assetstore.unity.com/packages/tools/utilities/pro-draw-call-optimizer-light-16888
Its free and will work with diffuse objects; try it out and do some tests with diffuse objects and if it works; you can purchase ProDrawCall which you can find here:
https://assetstore.unity.com/packages/tools/pro-draw-call-optimizer-54360

Do let me know if you have any other question ;-)

 

The shader I am using for my objects's material is the Tesselation/Standard Distance material, does ProDrawCall optimizer tool work with that shader?

Regards,
Carlos

 

It should work. did you tried out your project with the light version and diffuse?. which shader are you trying to use specifically? any from the asset store?.

If the shader you are trying to use uses textures, it should work. now if its a shader that came from the asset store and has the name "standard" in the shader itself; there could be some conflicts. if you want drop me an email to discuss more in deep.

 

I am using Unity 2017.2 for Xbox One. The material works well I just need to create atlases for the different textures and that my models's UVs match the atlases's position. I didn't try the free, because it wouldn't make any difference if it works for diffuse, since the actual shader I need it to work with is the tesselation one

Regards,
Carlos

 

Are your UVs inside [0,0-1,1]? if they are they should work. Unfortunately I dont have access to xboxone builds. I'll contact you through email to discuss more in deep that specific shader.

 

Can I clarify?
ProMaterialCombiner++ includes:
- Batch mode: Combine several objects materials.

 

Hello ivolga.

The batcher basically means that you can set up a set of objects with multiple materials for combining and the tool will queue and process them.

hope it made it more clear

 

Yes. Thank you.

 

Can I use it in Runtime?
