tree texturing

[hussainmv]

How to fix this? I'm importing FBX tree unigine. But the alpha and texture coordinates do not work.

I will share the same file in 3ds Max viewport preview and a Vray rendered file. @unigine_tutorials @unigigine

is your alpha a separated file ? it should be the alpha channel of the albedo or eventually B chanel of the normal map. 

[hussainmv]

how? @romain.janil

[werner.poetzelberger]

You need to copy the content of the alpha texture into the alpha channel and export a file format, which supports alpha channel. Eg. tga, tiff, .dds etc. in your Image Manipulation Software e.g. Adobe Photoshop.

Alternatively you could make the albedo layer transparent, using the alpha image as selection and use e.g. png or .psd format, in your Image Manipulation Software e.g. Adobe Photoshop.

In the engine you need to make sure that the texture is imported in the correct way, ideally transferred into a dds format uncompressed RGBA8 or compressed DXT3, DXT5.

You cannot use a separate alpha texture in the standard material. I guess you can design your own material or shader if you prefer to do that.

Import 3DS MAX FBX. but you have the same issues. have an alpha texture tutorial?

[hussainmv]

Uv mapping also does not work! Any solution? @unigine_tutorials

This is pure content editing.

There is nothing wrong with Unigine or fbx import.

Texturing and UV editing is basic Knowledge in the CG world and you should find Millions of tons of infos about that online

Keep learning ;)

here a setup for an alpha channel in PS.

@hussainmv Could you upload the .max file for the tree so I could have a look to see what the problem might be?

Thanks!

@hussainmv Thank you for the files. Will have a look today and report back. ;)

@hussainmv I tested your files and the ruh.fbx imports without any issues on my end including correct uvs.

These are the import settings I used:

Spoiler

The only thing I had to do was to use Photoshop and put the separate alpha texture for the leaves into the albedo textures alpha channel.

Spoiler

After importing the ruh.fbx go to the created materials folder, select all 3 leaves and change the preset to Alpha Test and enable Two Sides under the materials Common tab.

The final result:

I organized the textures and used Unigines naming scheme to make the textures more readable.

Hope this helps.
