Who make mods for SA know how bad SA's engine handles textures alpha textures.Those models who have complex alpha textures for hair , beards , lashes and etc look "bugged", with some "invisible" , see through parts. After 2 years searching , reading tons of articles, forums etc and tryin' tons of tricks , this is the one you'll have the best result.
I'll teach you how to solve this problem ( at least for most of the models because it didn't work for a small percentage. I didn't test it using z modeler but it should work as well.
- TXD Workshop
- 3ds Max
Open 3ds max, be sure to check that letter "a" and import your model ( in my case is one already rigged)
Important: Don't apply your hair texture now, Leave the hair textures to the final part!
The face texture
Now select your hair mesh
and then click on your model
And you'll have 2 models. A static one that with 2 hair meshes( one flipped and another one unflipped) and one rigged model ( with only one hair mesh). Select the rigged one you just imported, click on editable mesh and vertex.You'll see all those blue dots:
Press crtl+a to select all dots, they'll become red as you can see bellow:
Next,click on "attach"
After that , click ok and you'll have a new image there with "hair" name on it plus the alpha channel
In this tutorial, we double the meshes ( for hairs, beards etc) to get it working good since SA can't handle double faced polygons. So doing tihs trick both side of the mesh will be rendered without bugs. Plus using the right settings on TXD file, you'll make the result even better.
