  1. OK, got it
  2. Anyway, I can do it like this. But another problem: I can't merge all resulting material node together for rendering. This is causing shading errors. I can display one material at a time and render the whole thing with proper material assignment on one set of primitives. As soon as I try to merge two material nodes together…shading issues. I need to blast the primitives depending on their group. So how can I blast them based on this selection expression? @shop_materialpath=="/shop/Cruiseship_cleanup_v003_rpr:Glas_Grey_DisplaySG"
  3. ATM I have to use the "@shop_materialpath==..." eypression which is handier than selecting every object but I still have to write out lots of material names and then create them manually. No idea of python
  4. I didn't ask for an OBJ but the fbx seems to be corrupted. Well, I'll see.
  5. That doesn't sound very comfotable when you have to deal with hundrets of materials
  6. Hi, I guess thats a pretty easy question but I couldn't figure it out yet. So I have an obj import that consists out of a big amount of pieces. Importing it to other apps brings in the materials too. So I just can work on those materials insteat of reselecting everything. Importing that obj to Houdini doesn't show any materials. Why is that?
  7. Hey, I need a bump map to repeat on each primitive of an object. Not I can use an uv flatten in a for each loop and apply a map onto each prim. That works with simpler scenes. But on my scene the loop has to make 600.000 passes + it tends to crash. Does anyone know a way to increase the speed of this process or a better, faster way? Cheers!
  8. Thin I got a soltion
  9. Hi I have to work on and animated piece of cloth where the individual square pieces are docking into the animation. How would you go about the rendering? I got an attribute that separates bright pieces from the dark ones. Can call that attribute into the shader but need more variation. Would you use a for each loop to iterate over each piece in order to apply e.g. individual uvs for each piece? The material should be very sparkly on some parts.
  10. After some time worked on that thing again. Could need some lanterns for warm light
  11. Well, the card speeds up unter pressure - like the cpu or whatever. It just doesn't with opencl. Its a titan x maxwell hydro copper. Standard overclocking from the manufacture is @ around 1375 mhz. I overlocked it to even 1500 MHZ. Houdini's opencl is pushing the card to only around 1100 MHZ. Same problem with the 1080 ti. Its running at a max of 1400 where during gpu rendering or gaming @ nearly 2000.
  12. Nevertheless annoying that the opencl support isn't running the turbo mode of the card.
  13. Well, much more accessable VRAM due to not being responsible for a display. So I don't know how much of that 11 GB you effectively can use when the card runs a lot of other things + the viewport..but probably around 6 GB are REALLY free? The titan gives me much more space.
  14. Talked to the support. The only thing that works is to extend the code a bit:HOUDINI_OCL_DEVICETYPE = “GPU”HOUDINI_OCL_VENDOR = “NVIDIA Corporation”HOUDINI_OCL_DEVICENUMBER = 1
  15. It shows me the cpu and both cards. now need to know how I effectively can change the device. Changing device in the shell only tells me that the other cards gets used without really utilizing it.
