IPR Refreshes for no reason or too often

V-Ray V-Ray GPU Issues

Hey there,

Im having an issue with Vray IPR in GPU mode where the scene will constantly refresh whenever you move your mouse over the frame buffer or move the window - (Track mouse is off) (Rescale framebuffer) is off also. im not sure whats causing this but its become a complete headache. Cannot even use IPR like this.

Hello,

If this is in 3ds Max - do you have instanced physical cameras by any chance? There was a Max bug that caused infinite refreshes with instanced physical cameras that is fixed in Max 2020 (I think, might be 2019 too).

Best regards,
Yavor
