XRM Posted January 2, 2015 Share Posted January 2, 2015 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? Quote Link to comment Share on other sites More sharing options...
Guest tar Posted January 2, 2015 Share Posted January 2, 2015 if it's recent, what has changed recently? i.e. video drivers, Houdini version etc Quote Link to comment Share on other sites More sharing options...
XRM Posted January 2, 2015 Author Share Posted January 2, 2015 (edited) if it's recent, what has changed recently? i.e. video drivers, Houdini version etc 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.

Guest tar Posted January 2, 2015 Share Posted January 2, 2015 Can you please post your scene and exact computer specs - i.e. windows version, driver number, card, Houdini version etc. Thanks! Quote Link to comment Share on other sites More sharing options...
XRM Posted January 3, 2015 Author Share Posted January 3, 2015 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. Quote Link to comment Share on other sites More sharing options...
edward Posted January 3, 2015 Share Posted January 3, 2015 Try this first: - Ensure no Houdini apps are running - Rename the houdini13.0 directory to something like houdini13.0.old in your documents folder - Start Houdini If that doesn't work, then try changing the viewport GL version in the main preferences > viewport. If that doesn't work, I'm betting that it's the video driver version that changed. Quote Link to comment Share on other sites More sharing options...
XRM Posted January 4, 2015 Author Share Posted January 4, 2015 you were right edward. My graphics drivers were set to autoupdate. Reverting back to the previous drivers fixed it. Quote Link to comment Share on other sites More sharing options...
Suay Posted January 19, 2015 Share Posted January 19, 2015 Hello, Im having the same issue at the moment. Can you tell me exactly which driver you rolled back? Ty Quote Link to comment Share on other sites More sharing options...
malexander Posted January 20, 2015 Share Posted January 20, 2015 I've added a small workaround to the VDB SDF shaders to avoid an AMD GLSL compiler bug. It is fixed in Houdini 14.0.220 and 13.0.663. Quote Link to comment Share on other sites More sharing options...
