Corona Renderer 7 for 3ds Max - Daily Builds Discussion

[LorenzoS]

hi,
i am using the last corona daily built, but the materials converter don't work well in some cases,
there is a way to use the previous materisals converter without unistall the last corona daily build?

thanks

Hi

2 latest DBs IR works very laggy with Forest Pack 7. With FP 6 IR works fine

boy this new material converter really stuffed up my materials!  what is wrong with it?  its all over the place.

It's not done well. It fully ignores the use of Reflection slot (Instead of mapping it to IOR using few possible methods) and so the new materials don't match if reflection map was used at all.

Other issue could arise from being able to recognize metallic materials, but that's the issue with people using "No Fresnel" method for non-metallic materials (like DesignConnected does for example, by using Fallof Fresnel in Reflection slot for non-metals and IOR 999).

Hi Guys,

Can you please send through the scene(s) in question (before the conversion) and we will look into it.

Thanks,

Rowan

JFYI this is a really old version of the converter and could cause issues when using it with the latest version of Corona.

If you have a scene where the converter doesn't work well, please could you send it to us? Instructions can be found in my signature.

The material converter, removes from some materials the base color map,also when im pressing show selected maps in viewport its not working ,and after converting the scene all base color maps are not visible

Well... there is nothing to send :- ). The Converter doesn't account in any way for "Reflection" slot because new Material doesn't have one, and nearest equivalent is IOR. But mapping (Clamping) reflection shouldn't be considered "fake" per se and rather translated into IOR. Plenty of dielectric materials require mapping reflection to create illusion of depth.

Real world materials do indeed only vary roughness and surface relief, but with CGI Shaders we're faking information that geometry simply doesn't have. With that in mind, even mapping reflection is physically correct to real-world matched counterpart.

There is thread somewhere else on this forum where work-around was found in different ways, most common simply mapping IOR with Mix-Node. Dubcat did lot more complicate OSL setup, which sadly isn't universal enough (Since majority of 3dsMax don't even feature OSL and it could introduce lot of perfomance issues).

it looks not good.. where can I turn it off?

Hi,

Thanks for the feedback, currently you can't turn it off. But we are working on a fix so that it will become less noticeable. Stay tuned.

If you re-run the installer it should magically appear ;)

There are a couple of crashes we've encountered and are already working on fixes for compatibility with Max 2022.

Thanks,

Just asking out of pure curiosity but I'm wondering, is it possible to have the first couple of passes render oldschool style and then the rest do the new bucket thing?
