multisubobject material + vrayhdri map = viewport slowdown

[leo.surrealismo]

as the title says, when you have a multi/sub-object material with just simple jpg textures on the slots, changing from shade to wireframe is fast and viceversa.... but if you convert the textures to vrayHDRI the viewport performance is terrible.

has anyone experience this?

I´m using 3dsmax 2016 and latest vray build.

something I forgot; the textures are located in a network path

anyone? I tried it in another computer and behaves the same.
would this be a bug? nobody uses multi/sub-objects material?

The current project I'm working on behaves exactly like you describe : long lag when switching from wireframe to shaded and vice versa. I'll check tomorrow the scene to see if I have used vrayhdris in multi/sub-objects materials.

I've more or less the same problem (basically, 90% of our mats are multisubs). Extremely long file loading time if I show all textures, and hiding all textures is really fast. (No bitmap paging, max 2016)

I initially thought it was my graphic card so I've ordered a new one

[leo.surrealismo]

for sure is not the graphics card. I have 2 different video cards and the problems persists.
Is there a script to revert a vrayHDRI texture input to a normal texture input?

I guess I'll have to try GTA V to use my new toy then

Not that I know. But that would be useful indeed or better still, correct this bug

Hello!

It will be very useful if you could send us a simplified scene that presents the issue. We haven't been able to reproduce it so far.
I observe a small lag only during the initial loading of the maps in the viewport. Further switching between viewport modes happens immediately.
You can send us the files to support@chaosgroup.com or margarita.stoeva@chaosgroup.com with link to this thread.
Thank you!

Best regards,
Margarita

I'm uploading a scene right now, but it won't be simplified since the problem might not happen with all the textures.

I'll send a mail with the link as soon as it is online.

I also sent a simplified scene that has this same problem to margarita.stoeva@chaosgroup.com

file sent!

Thank you,
Philippe, Leonardo and Karim for sending your scenes. I appreciate it!
The scenes were sufficient for reproducing the issue and it is now logged in our bug tracking system and forwarded to our developers.

Best regards,
