IMPORTANT NOTE
The Corona Converter is now maintained and developed by the Corona Team. I decided to stop dragging it out any further. As you may have noticed, updates and fixes were rather slow and quite far apart. The reason is that I haven’t been using Corona in quite a while, mostly because my focus shifted more towards other DCCs where Corona does not exist. So, I fell behind following the news and changes that have been made in Corona and at this point I have missed many things that should be reflected in the converter. I think that it is unfair to the users to let the converter wither like that and asked the Corona guys if they wanted to take over - which they thankfully did .
Long story short: As of now, bug reports and feature wishes go directly to the respective forums.
Thanks to all of you for your support and the great connections and friendships I made here since 2012.
better fR_Architectural translucency conversion by Rawalanche (+ glassmode)
better MR_ArchAndDesign translucency conversion by Rawalanche (+ glassmode)
I’m still struggling with the Vray translucency conversion since converting system units into some “scalar” value doesn’t make sense to me :-/
Thanks for your more detailed MR translucency conversion technique Rawalanche, it helped a lot
I’m happy to hear that I didn’t test it so much on “real” production scenes yet. If you have any suggestions how to make conversions better, don’t be too shy to tell me
fR changed a lot since R2, so you should at least have 3.5 to be sure the converter works. I don’t know what could be wrong or not working, so if you have any error messages in the Listener, please post them here or to me via pm
What do you mean? Normally you should just have to press the button and that’s it Conversion results may of course differ from your original materials since corona mats don’t work exactly like fR_Advanced or other shaders. So you may have to correct some things by hand. But all in all it works pretty well without to much additional fixing. It’s also depending on the maps and plugins you use. The script tries to convert vray specific maps (since corona does not support them) but there is currently no conversion for fR maps or fR materials apart from fR_Advanced and fR_Architectural (since there are so many of them in fR).
I checked the fR methods again. With my fix yesterday I killed a FR_Architectural function :S. There was not much fR functionality testing since I don’t have fR at home (i can only test that while being at work )
Since Corona is crashing when you use a normal map somewhere in your materials I added a normal map warning with the ability to chose to replace those with a “empty” black color.
changelog:
*v0.10
added a “normal bump” map warning with replacement functionality
I found some weird behaviour with glass conversion from vray material: everything in corona material is set correctly, diffuse/reflection/refraction except obviously the twosided check , but the material preview slot appear black, if the refraction value is 0. Resetting the material in a new corona material solve the problem. Everything else works fine.
mhhh.. I’m not sure what you mean? I tested converting a refractive material and I don’t have any problems here. Could you be a bit more specific which material you’re trying to convert? A Screenshot of an example material would be very helpful.
Here you an example. I found that the problem could to be the fog color in vray material. Maybe because in Corona there’s no value like that, in fact I had problems achieving the same effect on another scene, building the material from scratch. I tried to change the refraction color, but it will affect also the “amount of refractiveness”, I ended up with too much a bright color.
Settings in the hidden tabs are at default values.
Aaaah, ok. Yes, I’m pretty sure it’s caused by the Fog/Absorption conversion. This is indeed a problem and I fear it’s not so easy to solve. Those two work kind of different. When I set a Vray material to 0.001 multiplier there will be almost no visible effect at all. If i do the same thing with corona it absorbs everything right below the surface. I’m not sure if there is any reasonable way to convert those values… I could make a checkbox to ignore fog but I’m not sure if this would be a great help.
It looks like the script doesn’t like converting groups. If I open the group, deselect the group, select the objects, run script is works.
I’ve seen it happen a couple of times. Just not a 100% its just a group thing.
Javadevil: Who the hell is using groups hmm… never tried that since I’ve never used groups for several (imho) good reasons. I think I know why this happens but I will have a look on it, thanks for reporting
Hehe Yeah I know Groups can be dodgy, but there quick and easy to use and with the Outliner script I can select objects in side the group without opening it.
It would be nice if we have an option to automatically reduce the blurriness of the maps with a value since corona doesn’t deal good with the blur value ( about 0.3 or 0.2 is a good value for now )
