  1. I have a small compositing network which I want to reference as texture in the shader using the op: expression .ie op:/img/trail Even though I've managed to make it work several times, I always find it a bit flaky and many times mantra doesn't manage to load the image, even though it may be visible on the viewport when referencing the same image operator in a uvquickshade node, or just by loading the shader. It works with a principle shader out of the box, but if I put the same shader within a material builder it breaks. Is there a render attribute or something else I need to add to the shader? I understand it's better to use pre-rendered images the normal way, but I want to use dynamic heighfields SOPs for textures and ideally avoid having to write out thousands of frames in advanced.
  2. Hi! I'm new to HDK and starting with some samples. I managed to make several samples such as SOP_Star.C work but failed to compile IMG sample which is a plugin used to add new file format support to houdini. I'm useing VC14 and Houdini 15.5.717 I'm compiling with nmake, Makefile and command line tool of Visual studio 2015. And whenever I try to compile IMG sample with command "nmake Makefile.nmake", it tells me " 'sesitag' is not recognized as an internal or external command, operable program or batch file. NMAKE: fatal error U1077: 'sesitag' : return code '0x1' " Any idea how to solve this out?
  3. Forcing file load via Python

    Hi I create a small python script in the filename entry to load my files. The python code returns the correct file name and path in the filename box. It is all good. But the problem is that I cant get it to load files automatically as the frame advances. I ahve to manually press "reload sequence" on every frame. Please bear in mind that the file names are generated at each frame by reading file names in certain folders so there is no pregenerated file scheme. I tried hou.iu.triggerUpdate but that did not do anything. I also tried the to eval the Reload sequence parm which is reload. That did not work either. I am hoping that someone here might have a better suggestion to get the reload going. Because as of now I cant render. Render out or Rop out does not work because it is not loading the files ;(
