Frame buffer lag on using OCIO

[Muhammed_Hamed]

Hi,

Using OCIO in Vray's frame buffer in Modo, it gets very lagy when panning the view. See here,

This doesn't happen in other Vray plugins, can this be improved somehow? or is there a workaround?
I can attach the EXR I used if needed. Let me know

Best,
Muhammed

Hey, Muhammed,

Thx for the feedback is there a chance to get the *.ocio file?

What build are you using for V-Ray for Modo, Maya, Houdini ?

Are you sure both the image size and all OCIO settings are exactly the same ?

What build are you using for V-Ray for Modo, Maya, Houdini ?

4.3 builds for all
Vray for Modo nightly build >> 25th of April
Vray for Houdini nightly build >> 7th of April (nightly branch)
Vray for Maya build >> Not sure, but it is from end of March (stable branch)

I can test again with latest nightlies for all, if needed.
I've pointed the VFB in all 3 to the same folder, it is the exact same .vrimg file

With Modo the CPU usage goes very high when I start panning the view.

Yes it is the exact same settings and the same .vrimg file, In all Vray plugins I set color corrections to be loaded automatically in History when I click on an Image.
