custom shaders with 4 layers using vertex color and mask for gta IV

Hi guys. I would like to present to you the shader I created, which can create terrain from 4 textures using a mask and vertex color.

Video

Reflections and lods transition also work.

Added shaders with stippletexture support. Made for RevIVe.

_________________________________________________

 

Parallax will not be added. In fact, I can implement this and for this GTA 4 supports the second RGBA channel (position, normal, color1, color2...) openIV supports only one, so the shader with parallax is not published here. Assemble wdr with two RGBA channels without openiv is possible, but it will take more time.

 

_________________________________________________

 

First, add lines from the archive to preload.list, as well as to ShaderManager.xml, which is located С: \ Users \ username \ AppData \ Local \ New Technology Studio \ Apps \ OpenIV \ Games \ IV \ openFormats

.ms files to <3ds max folder>\scripts\ofio (To edit models using OFIO).

_________________________________________________

 

The mask of the layers uses UV channel 2

Light blue is used instead of red

 

texturesampler_layer0  - diffuse texture

bumpsampler_layer0 - normal texture
specsampler_layer0 - specular texture

texturesampler_layer1  - diffuse texture

bumpsampler_layer1 - normal texture
specsampler_layer1 - specular texture

texturesampler_layer2  - diffuse texture

bumpsampler_layer2 - normal texture
specsampler_layer2 - specular texture

texturesampler_layer3  - diffuse texture

bumpsampler_layer3 - normal texture
specsampler_layer3 - specular texture

lookupSampler - mask texture
specularfactor - specular glossiness
specularcolorfactor - specular intensity
bumpiness - normal map intensity

_______________________________________________

 

Test model so you can look at the shader in the game.

In essence, this shader works as a terrain shader in gta V and can be used to convert map from gta v to iv.

Also in a few days I will add: terrain_cb_w_4lyr_2tex_blend.fxc, terrain_cb_w_4lyr.fxc terrain_cb_w_4lyr_spm.fxc(added)

To avoid the error "EXCEPTION: Map support not enabled for specific map channel: -1", set the white color in the Illumination channel

I may not come here often, so for any questions or errors in the shader you can let me know in Discord: Іван Іванович#8929
