trashcan Posted November 18, 2021 Share Posted November 18, 2021 I'm using the wonderful ProjectionViz tool to illustrate clipping for a client. Unfortunately, it doesn't seem to work properly with Image Props: The image props cast shadows but they don't seem to receive the projected image. It does work for extruded solids, though: Any ideas? 1 Quote Link to comment
Kevin Allen Posted November 18, 2021 Share Posted November 18, 2021 Image props usually have a constant reflectivity, which kind of prevents seeing how any light affects the image. It also keeps the crossed planes from being visible. You can try to correct with a different reflectivity shader and not using crossed planes. 2 Quote Link to comment
trashcan Posted November 18, 2021 Author Share Posted November 18, 2021 I'll try that out, thanks @Kevin Allen Quote Link to comment

Is that a custom test pattern? I haven't updated PV yet... Quote Link to comment
trashcan Posted November 18, 2021 Author Share Posted November 18, 2021 Mission accomplished - changed the Reflectivity of the image prop to NONE. Crossed planes doesn't matter. 1 Quote Link to comment
trashcan Posted November 18, 2021 Author Share Posted November 18, 2021 @Mark Aceto yeah it's custom! one of my test patterns. looks great when rendered, but not super great when messing around in OpenGL (now called "Shaded" - why the change VWX?). ProjectionViz's default test pattern is definitely better for roughing it in. Only high contrast shows up in GL and only display black + white, this isn't a bug, just how PV works! 1 Quote Link to comment

It's Metal on Mac and DirectX on Windows. I'm trying to buy a PV license right now. I'll download the trial in the meantime. I know there are some weird things with OpenGL / Shaded and shadows (try unchecking shadows in Shaded options). 1 Quote Link to comment

JBenghiat Posted November 18, 2021 Share Posted November 18, 2021 For the moment, Shaded render replicates OpenGL, so shader shadows are bitmap (B&W) and reversed (black is allows light to pass). 1 Quote Link to comment
