Maxscript question to Vlado

[SylvainJ]

Hi,

I just want to know if I can access different G-Buffer channel of Vray via Maxscript ?

I try the .gbuffer_channelMask but it doesen't seem to work properly.

example, if i assign the vr variable to the currect renderer and I enter this command :

vr.gbuffer_channelMask = 3

Nothing append.
but if I enter this command:

vr.gbuffer_channelMask = 4

Now the z-buffer channel is highlight.

is there a way to make this working ??

Thanks

Each bit in the channel mask corresponds to one channel; I think 1 and 2 are RGB and alpha, which are always generated anyways - this is why a value of 3 does nothing, but 4 switches on z-buffer. Higer values (8, 16, 32 etc) correspond to the rest of the channels.

Best regards,
Vlado

I tinkered with it some time ago, I wanted to integrate Vray into the Max 7 Render to Texture dialog properly and provide all the passes native to Vray. I never finished it since the project I wanted to use it for was cancelled, but here is what I found out (not documented in the help files).

1 N/A (RGB?)
2 N/A(Alpha?)
4 Z-Value
8 Node ID
16 Material ID
32 Material Color
64 Material Transparency
128 Normal
256 Real RGB
512 Object Velocity
1024 RenderID
2048 Coverage
4096 Sub-Pixel Weight
8192 Atmosphere
16384 Background
32768 Diffuse
65536 Reflect
131072 Refract
262144 Self-Illumination
524288 Shadow
1048576 Specular
2097152 Lighting
4194304 Global Illumination
8388608 Caustics
16777216 Raw Global Illum
33554432 Raw Lighting

Hope that helps,

Hi metroberlin,

I've only created a more simple dialog render launcher with all the presets for the interior and the exterior for the other people here because they don't want to lean everythings in vray and when they choose the render a rpf file, a dialog open with all the options for the rpf format. If they choose the Z depth option, automaticaly, the z-depth is set active in the rpf file and in the g-buffer section of vray.

It's only this
