problem bumpmap glass material
« on: September 18, 2013, 05:46:50 am »

Hello,

I added a bump map has KeyShot to fit holes in a water bottle.
rendering problem when I zoom the picture there is the small waves (see picture)

What do you think? how to eliminate it?

thank you :)

Hi,

It's hard to say. Would you be able to send us the BIP and the bump map as well? If so, please use https://keyshot.wetransfer.com/ and send to [email protected] or [email protected]

Thanks,
Chad

Hello,

thank you for your answer

Unfortunately this is a project agency, I can not transfer files.
I just saw that the problem comes from the displacemap. not everything is great, there is a problem, maybe the problem comes from the generation of displace?

Okay - well, you may need to bump up the quality of the displacement map or subdivide a couple more times before exporting. Depending on how close of a shot it is, you may get by using a bump map here.

effectively

UV remapping, export of diplacement 32-bit (instead of 8) and OpenEXR rendering is top!

;)  thank you
