normal and bump map support?

[Andy Mac]

Just a quick question.

I exported a vrscene from 3ds max with a normal map plugged into the bump slot,(with the normal map node inbetween the bitmap and bump slot) but it didnt appear to import into Lavina. Is the bump slot supported yet?
Thank you

Normal maps are not supported currently.
And bump mapping supports only file textures, no procedural textures of any kind.

We will be working on improving this later this year, most likely.

Hi again.

I'm having trouble getting bump maps to work also. I've attached my test scene, bump texture and 2 images showing the vray and lavina output.

Any ideas what i'm doing wrong?

Best regards,
Andy

Hi Andy,

Bump renders somewhat different than 3ds Max. This is on the "To do" list. You could try increasing the global bump multiplier in the render settings, but that will not always work.

Can you attach your example scene again or send it to my e-mail ?
I can't download it for some reason, maybe the forum doesn't like the 'rar' extension.

It will be useful when testing the improvements once we make them.

Thank you both!
I'll try increasing the bump map multiplier further to see what happens. I'll also email the scene across to you Vladimir.
Thank you

Increasing the bump didn't work unfortunetly (raised it to 1000%) but i did try replacing the vray material with a 3ds max standard material and the bump works as expected.
Not sure if the following information will help, but i'm using

• Vray 5 hotfix 2
• RTX 2080 Super
• GPU drivers are version 442.92
• Lavina - v0.4.2, build 742011, hash 569ec219

Thank you

Thank you, the additional information is useful. There is a known issue with the bump handling from V-Ray 5. We will address in the short term. However, please note that the result of the bump between V-Ray and Lavina will be somewhat different. Here's an example of the difference.

As a work around, if you generate vrscenes with V-Ray Next you'll be able to see the bump in Lavina.

Thank you very much for the info.

Again this is good to know and i look forward to future updates.

Thanks
