Full texture vs. On-Demand mipmapping - not like expected (V-Ray for Rhino)

[Micha]

Most I used on-demand mipmapping but today I switched to full textures and wonder about the lower memory usage:

on-demand mipmapping (8bit) ... 7860MB
full texture (8bit) ... 6470MB

I tough on-demand mipmapping is for saving memory and now I see it increase the memory usage. Any ideas what happens here?

This does not look normal. Best send the scene in question to support@chaosgroup.com so we can take a look. Mention this forum thread in the e-mail along with your V-Ray and host platform versions.

Hello, Micha ,
As my colleague mentioned, it would be best to send over a scene or at least a stripped-down version of it that still exhibits this problem.
In addtion to this request, could you please confirm which V-Ray for Rhino version you are using (4.20.03 or 5.00.b2)?

Kind regards,
Peter

Peter.Chaushev I used V-Ray for Rhino 4x. Should I test it per v5 and only send the file if the issue is there?

[Peter.Chaushev]

This behavior should not occur with V-Ray regardless of the version that is used.
If you agree to send over the scene, our support team will conduct the investigation. Please be sure to pack the project to ensure all image files used in the scene are archived together.

Peter.Chaushev I send a link of the file per support ticket 320-363-8189. The scene is available until 23 oct 2020.
