vray CompTEx for Maya

[alexitoland]

Hi ,
I couldn´t find the shader vrayCompTex for Maya, is that shader implemented for Maya?
Thanks,
Alex.

in the past i have been told to use the layered texture instead. however i've noticed a bug that can sometimes add a black empty layer to the layered texture. makes it pretty frustrating. so look out for that.

No, but you get all the other nodes in Maya (multiply/divide, plus/minus/average etc), which do pretty much the same thing.

Ok , I see anyway woudl be great to have t implemented for Maya , it would be easier specially when trying to replicate Vray Max shaders.
Thanks,
Alex.

you may want to explore -- create/vray/create texture from a plugin/ compMaxTex

this is a replica of max comp tex in a plugin form. May do the trick for you?

I saw that too, but there isn't much explanation anywhere for this plugin.
Does anyone know what Operator "0" is?
I'm looking for VRayCompTex's "Minimum" Operator.

hi,
based on this doc http://www.spot3d.com/vray/help/150S...tex_params.htm
i would try nr. 6 so mode 5 should do the trick?!

but just guessing . ..

Use the plgparams utility to view the description of the parameters for TexCompMax:

C:\Program Files\Autodesk\Maya2012\vray\bin>plgparams -plugindir ..\vrayplugins TexCompMax
Parameters for plugin 'TexCompMax'
  compatibility_with: integer = 0, This is used to differentiate between texture s exported from different applications. The value means : 0 - 3ds Max (this is also the default), 1 - Maya, ...
  alpha_from_intensity: integer = 0, If 2- the alpha is forced to 1.0f; 1-the resulting alpha is the color intensity; 0 - the alpha is taken from the bitmap alpha
  invert: bool = false, If true, the resulting texture color will be inverted
  invert_alpha: bool = true, If true and invert is on, the resulting texture alpha will be inverted too. If false, just the color will be inverted
  color_mult: acolor texture = AColor(1, 1, 1, 1), A multiplier for the texture color
  color_offset: acolor texture = AColor(0, 0, 0, 0), An additional offset for the texture color
  alpha_mult: float texture = 1, A multiplier for the texture alpha
  alpha_offset: float texture = 0, An additional offset for the texture alpha
  nouvw_color: acolor texture = AColor(0.5, 0.5, 0.5, 1), The color when there are no valid uvw coordinates
  color: output acolor texture, The resulting color
  out_transparency: output acolor texture, The resulting transparency
  out_alpha: output float texture, The resulting alpha
  out_intensity: output float texture, The resulting intensity
  sourceA: acolor texture, Left hand side texture.
  sourceB: acolor texture, Right hand side texture.
  operator: integer = 0, 0:Add, 1:Subtract, 2:Difference, 3:Multiply, 4:Divide, 5:Minimum, 6:Maximum

nice!

thx

the black layer bug I think is now fixed since version 2011 of maya.

hey
hope someone still reads this post ^^

how do you overlay two textures - blend mode "over"
like the default blend material does ...

[mayanic]

btw - do we get all the textures, shaders and plugins in vray 3.0 for maya that max has?!

or do we still have to use the legacy system via create menu?

[vlado]

Whatever is not exposed in the UI, you can get from the Create menu, yes.

Best regards,
Vlado

[mayanic]

yes, i know
but will they be integrated?!

and how would you do a simple over?! kind of blend material's sister - a blend texture node . .. to comp two textures - one on top of the other - based on an alpha channel?
i fear comptex doesn't offer that option???

Have you tried to use the Layered texture as mentioned earlier in this topic?
