  1. Double-sided materials

    or you can use "Two Sided VOP"
  2. bakeTexture SurfaceColor(cf)

    unfortunately there is no straightforward way. you would have to build it again in SOPs or render the texture and use it as a source for point colors. theoretically you can copy an paste nodes from mat net to VOP SOP but that generaly doesn' t work well. shame .-/ other way around - from SOP to shader it's very easy thou just by reading geometry attributes.
  3. Clarisse iFX ?

    from what point of view do you want to see it? clarisse and fusion are two very different products and I don't think any general comparison is relevant.
  4. Arnold in houdini Errors

    hard to say whats the problem without seeing the scene. anyway it looks like you're mixing arnold and mantra nodes together. raised errors complaining about principled shader suggest that. also, lights in your scene seems to be mantra lights. those obviously can't be rendered in arnold
  5. bakeTexture SurfaceColor(cf)

    use baketexture ROP then
  6. bakeTexture SurfaceColor(cf)

    don't bake Cf. pipe surface color into arbitrary channel and render that as a custom image plane. predefined channels never work for me when baking (or maybe i just did not understood how it's supposed to be used)
  7. in Render tab on your object you can set Render visibility to "-shadow". that makes an object invisible for shadow rays.
  8. Bad Parameter Reference Error

    it looks like you are referring to parameters/nodes that don't exist in your scene.
  9. hi, i haven't read the thread above but: 1 - I noticed render time increase with very large number of aovs (dozens). Otherwise, in typical cases I don't think difference is large enough to really notice. 2 - i don't think you are supposed to setup depth pass in any way. just allow depth in aov presets on mantra rop and it will do depth i think for a distance at which camera clipping planes are at. like world units. simple as that. then i comp multiply by whatever scale you need. see histogram to get min/max numbers.
  10. Background image

    dunno, works for me... i usually select a sequence from file browser and it just works if frame numbers are matching. tried it just now. expression is simply path_to_files.$F.jpg
  11. Background image

    that's probably bcs numbering of your files is wildly different from your timeline frame numbers. you have to compensate for that so those two match. so if you want that file background.098766.tga to be visible on frame 100 you need to type "background.`$F6 - 98666`.tga
  12. Background image

    filename.`$F`.jpg $F takes whatever is your frame number on timeline. $F4 will take that frame number with padding (i.e. 0001 instead of just 1) if you have different numbering you can use something like filename.`$F - 1000`.jpg
  13. Background image

    i think it's greyed out when you already have an image in perspective view in viewport display options. not absolutely sure, it shouldn't normally be greyed out thou
  14. Rendering light & shadow

    why don't you do two renders and then comp them together? sure you can get both in one render but that will require some setting up that you'll have to figure out
  15. Rendering light & shadow

    just use shadow matte material preset. that is the easiest way I guess.
