Title: Real World Map Size
Post by: klyde on 2013-11-27, 11:29:12

I use Real World Map Size option in 3dsmax, but I do not know how to make Corona materials show it correctly in material editor. So if there is no such option, I would be glad if it will appear.

Can you elaborate on what the option should do? I am not sure what it is for and what is the expected result ;)

basicly necessary add RWMS Mapping to Material sample shperes side by side with usual UV Maping.

Here is the difference.

Same problem. I tried to explain it here http://forum.corona-renderer.com/index.php/topic,1992.0.html

I don't understand in programming so it's may be funny for you. But if you see "v" near world-scale, may be it is possible to show in material slots bitmap 1x1 unit anyway?
1x1 unit material same for both kinds of mapping.

Let's say my diffuse bitmap AxB units. And Bump for example CxD.
So in materials slot I'll see diffuse 1x1, bump C/A x D/B and so on...

In case that we need only color for diffuse but have the maps in another slots, so A=C, B=D.
Something like this....

Sorry for my rich english :(

In Options for standard max material editor there are the options to Auto-select material texture size or Use real-world map size. In Corona this options are not working. Is it possible to turn them on?

isn't it just to make a global scale factor for setting the sample sphere when maps are set to Real World Map Size units  in the general setup aside with the quality setting for the sample sphere. in other words you set a size the sphere should represent globally when maps are set to RWMSU.

If maps are set to use RWMSU  then the sphere is set to show it in fx 2m x 2m (the setting set in the general setup.

The problem might be that you must handle the procedual maps so they follow the same scale relatively - but I suppose its the same problem you meet when you render it in the scene.

I never do that, but theoretically you may use world-scale map and usual map in same material with other channel IDs. Really problem. But today I make my materials as a blind, only by parameters.
