Corona to VRay: converting CoronaColorCorrection to Color Correction map

[TheAnth]

I am trying to convert my Corona model into VRay.

The only problem is that VRay Converter is not able to convert CoronaColorCorrection map to the classic Color Correction.

Is there a way to solve this issue?

I am using VRay Next 1.1 and Corona 4.1

As you can see from the attached picture, I have the same problem with CoronaBumpConverter.

Hi, are you having this problem often, or on a large number of materials? If so, I think this should be fixable with maxscript, however we don't really have any maxscript expert aboard.
I will see what exactly could be done here, as it also looks like something that should be improved in V-Ray <> Corona interoperability.

[TheAnth]

no at the moment I am having this issue only for this material.

Same for me, I am not an expert with maxscript, so I wouldn't be able to solve the problem that way.

Greetings, Alek from ChaosGroup's support team here.

I did a bit of testing and spoke to the developer in charge of the V-Ray convertor. The conversion of the mentioned nodes is not yet supported, however, we've logged them for support in our internal to-do lists. There should be a way to convert the nodes via MaxScript which I'll investigate and post the solution as soon as possible.

Great thank you!
It would be interesting to know this workaround with maxscript

By the way, the CoronaColorCorrect node is supported (CPU only) when rendering with V-Ray, so there may not be a need for its conversion.
