  1. Guided ocean not guiding properly

    Maybe your source node has time limited by expression. Check your source node. If that is not the case share your file here. I can have a look. Ranadeep FX TD @dNeg
  2. Bullet through viscous gel

    Hi everyone,I was trying to achieve a bullet passing through high viscous gel. I started with a keyframed bullet which passes through a flip cube. I am using the suction force option to make the flip particles retain shape. I can't get it right at all. Always particles are bursting out. I am attaching an youtube link to the reference.

  3. Hi fellow FX artists. I was recently doing a sim which required viscous liquids. I wanted to try the opencl option with helps to calculate pressure and viscosity on a graphics card. I am getting this error c:\workarea\16.15.2211\stream\opencl\compiler\clc2\ocl-headers\build\wNow64a\B_rel/opencl12_builtins.h:14603:36: note: candidate function not viable: no known conversion from 'const __global fpreal *' (aka 'const __global float *') to 'const __local half *' for 2nd argument half __attribute__((overloadable)) vload(size_t offset, const __local half *p); ^ c:\workarea\16.15.2211\stream\opencl\compiler\clc2\ocl-headers\build\wNow64a\B_rel/opencl12_builtins.h:14609:36: note: candidate function not viable: no known conversion from 'const __global fpreal *' (aka 'const __global float *') to 'const half *' for 2nd argument half __attribute__((overloadable)) vload(size_t offset, const __private half *p); ^ error: Clang front-end compilation failed!

  4. FLIP particles disappearing! one by one...

    Check the attached image. Turn that option on. It shows the collision sdf volume. I am sure the volume is not correct. Cheers!

  6. you were right edward. My graphics drivers were set to autoupdate. Reverting back to the previous drivers fixed it.
  7. The scene files are opening fine in the other systems. There is not problem with it I am sure of it. Even if I just add a box and then connect it to a vdb to polygons node, I can see this problem. I am on windows 7, Houdini 13.0.547, AMD R290 with latest drivers. It was working fine. I can only think of formatting and installing everything fresh again.
  8. Nothing. It just started happening all of a sudden. I even tried restoring and also deleted the houdini13 preferences folder from my documents folder. I even re installed the graphics drivers. All in vain.
  9. Hi, recently I am facing this issue. The display of sdf and distance vdb is always corrupted in the viewport. I've attached an image. Does anyone know how to fix this?
  10. Yes I am talking about point renders not mesh.
  11. That will again will be waste of time as the combined cache size per frame is more than 10 Gb. If I have to load everything why wouldn't I just render it instead of saving. You see delayed load is used to cut down the RAM usage.
  12. Hi all, I've this huge FLIP sim which I've distributed on 10 farm systems to sim. Now I am able to load them using the loadslice node that houdini creates for distributed sim cache loading. What it does is it basically loads each and every slice and delete repetitive particles. It ia basically using a for each. Now my question is, can we do all of this using a delayed load shader or a instance shader? That will actually use less ram than loading the cache in a file node. Thanks for your help.
  13. issues with scaled camera and volumes

    Hi Florian, This a common thing in Houdini Scaling camera and light can cause this thing. Use the below mention expressions to fix it Unhide scale in camera and origin(opinputpath(".",0), "", "SX") for x origin(opinputpath(".",0), "", "SY") for y origin(opinputpath(".",0), "", "SZ") for z that should do it. Cheers!

    Thank you D K for the tip. It works fine now.
