IPR WIndow doesn't work (black window)

[Matteo_Leoni]

Hi,

my IPR Window doesn't work, black screen and no info in the IPR Window command line.

But when I start the render in the C4D picture viewer, it works.

I have Nvidia Quadro K620 with latest driver.

May you help me? Thank You

Check the Arnold log.

Was the IPR already open? Can you start a new, empty scene, create a sphere and a skydome light, set the verbosity level to Info, and then open the Arnold IPR window?

Do you have the viewport (Editor Window) open? There's a known limitation in the plugin, the IPR Window does not update when the viewport is not visible.

[Shawn_Kearney1 · Accepted solution]

This probably isn't the issue, but check your scale and zoom on your IPR. If it's a very small number then this will happen. I am not sure why, but this happened to me. I suspect that for whatever reason it was set like that and I accidental saved it into my new.c4d file.

Peter - Since we're on this subject, specifically my IPR zoom and scale are/were set to their minimums (zero and something like 0.01 respectively) I am pretty sure I would not have set these up that way, though anything is possible. If this is the case of Matteo as well, then maybe a bug?

[peter.horvath6V6K3]

I remember an issue in the past where the scale input was in focus when opening the IPR window, so typing or scrolling messed it up. But I think I've fixed that, at least I did not meet this problem recently. If you can reproduce it, just let me know and I'll take a look.

[Shawn_Kearney1]

For the next few weeks I'll be working in After Effects, but next time I'm in c4d I'll try to reproduce and report back.

[Matteo_Leoni]

Thank You Shawn, it works! I don't know why my IPR scale was 0% and then black screen on IPR! Now I set scale 100% and render works!

Thanks Shawn Kearney
