Texture not rendering(2.49.9 exporter)

[organic]

I can't figure out why the textures don't render on this object. It has two materials and one material has two image textures, one with an alpha channel.

The console shows the textures are being loaded:-

Tracing 1000000 image samples for light cache in 4 passes.
Bitmap file "../../applications/Blender/lib/tex/MetalPlate02-Horizontal.jpg" loaded.
Bitmap file "../../applications/Blender/playbox/spanner/Fascia_texture-01.png" loaded.
Bitmap file "../../applications/Blender/lib/tex/Cloth/feltlike_material_150129-01.JPG" loaded.
Bitmap file "../../applications/Blender/hdr/HDRImaps-Dock/Dock-Sphere-FREE.hdr" loaded.

So this:-

Should look more like this(rendered with Yafaray):-

I'm using the 2.49.9 export script with Blender 2.49.2 on Ubuntu 8.10 64 bit and V-Ray for Maya (vray_adv_08529_maya2008_linux_x64)
I am new to rendering with V-Ray so I don't know whether it is user error or not.

Doest objects with these textures contain UV mapping? If no than they should.

and one material has two image textures

May be you should play with blend modes - they can differ from yafaray's.

I'll also check if its not a bug tomorrow =)

Hi and thanks.

One of the image textures has an alpha channel and reversing the texture stack so that the image with the alpha channel is applied last helps a little. Removing the other image texture helps a lot. Both images are UV mapped and both blending modes are set to Mix. Changing only the blending modes doesn't seem to resolve it.

Here it is with just one image texture applied:-

Try updated script: http://vray.cgdo.ru/files/vrayexport_2.49.9.py

Hi, thanks, that is a lot better.
It still only shows the texture image with the alpha channel if it is last in the stack, but I guess that is logical.
The problem now is that it doesn't seem to take any account of the Map To Col etc sliders. For the metal texture, I have turned down the Col slider to 0.18 but it still shows like this:-

The metal texture should be barely visible. The website suggests that the stable version supports what I am doing, but is this also the case for the 2.49.9 version?

Yep, Col slider is not supported.

Aha .

No problem, I'll make a single image texture in that case, thanks...
