Hi, guys I search a lot and didn’t find how to convert vray materials of some object to corona if I don’t have vray installed. I don’t wanna buy v-ray just to convert it to corona, it doesn’t make sense. Thanks for helping. ---

You don’t have to buy V-Ray - the converter works so long as V-Ray is installed, even a demo, even if the demo is expired. Also, many V-Ray materials render in Corona as expected without conversion too (and that does not need V-Ray installed). Hope that helps! ---

Wooo, it’s true. I hadn’t thought about it Thanks a lot! ---

I still find it annoying I have to install vray to convert materials to corona. Would it be possible for the corona installer to provide the needed files for this now it’s all the same company? Max UI is bloated enough as is, I don’t need or want to see extra vray features on right click menus, modifiers etc. 😃 ---

for any sort of class conversion to work in 3ds max, you need those classes to be recognized. to do that there is a need for a plugin to define those classes. (there is no need for those classes to have functionality just defining the class and its parameters would be enough). so for example, if there is no plugin to define the vraybitmap class it would not be possible to pinpoint that and convert it because it is undefined and pops the missing plugin window. it would be awesome if we could have just one (or many) plugins (optional during installer so the user can choose to install or not) to define those vray classes without any functionality just to do the conversion. same for the vray users to have a defining class plugin so there would be no need to install both at the same time. so +1 for me too ---

Hi all, just wanted to re-start this discussion as our team are currently trying to drop vray completely in favour of just using Corona only. Were’re currently using Corona 6/7 and vRay 5. Has there been any advancements in functionality of this sort e.g. In Corona 8? Seeing as it’s now Chaos Corona 8, and the amalgamation of the two products is getting closer year by year. Is there any mention of it on the current roadmap for future Corona builds? Regards, ---

You will always need the engine being converted from to be installed, so that the materials are readable (otherwise they will just be “blocks” with no parameters, as it’s the engine that makes sense of the data in the material). As ever, a demo, even expired, is perfectly fine. ---

maybe just integrate a demo version of vray into the corona installer and hide the installation procedure from the user?
