markerline Posted July 11, 2005 Share Posted July 11, 2005 Dear Users: I have tried to follow the candle tutorials from the Sidefx website which discusses creating OTLs and specifically discusses embedding a texture file into the OTL. I think I followed all the steps correctly, particularly the one where you have to specify your file texture as "opdef:/Object/object_name?texture_file.xtn". I'm not sure why when I load a brand new Houdini session and I drop a new OTL object on the stage that I can't get it to appear with the texture file. Is there a problem with the format that I used, which happened to be TIFF? Any help on this is greatly appreciated since I posted previously on wanting to learn how to embed textures into a file so that I could upload to this forum. Thanks in advance. -penciline Quote Link to comment Share on other sites More sharing options...
markerline Posted July 11, 2005 Author Share Posted July 11, 2005 I figured out what the problem was--I had some locked SOPs that were set to display. When I wrote the OTL the SOPs were locked but the texture was visible. Apparently, houdini needs to cook the SOP once within each new session to reference the textures? I'm still a little confused why I had to unlock the SOPs but I think this is the reason my textures weren't showing up. Someone please let me know why. Thanks. -penciline Quote Link to comment Share on other sites More sharing options...
spaceboyzero Posted August 1, 2005 Share Posted August 1, 2005 i`m having a similar problem, i`m trying to build an OTL but my shader sops were deleted a long time ago, so the shader paths are implicit to the geometry, this means that when i collapse the model to a subnet the shader paths seem to become dead and the shaders disappear from my model. if anyone knows a way that i can fix this without having to go through and reapply my shop nodes i`d be a very happy man! thankls, Mark I figured out what the problem was--I had some locked SOPs that were set to display.

edward Posted August 9, 2005 Share Posted August 9, 2005 You could use an AttribStringEdit SOP to do some low-level string manipulation. Quote Link to comment Share on other sites More sharing options...
