RC2 is up: fixed crash with corona bitmap inside composite map
Rendering is magic.

the corona bitmap has a view bitmap option like standard bitmap?, in cant seem to find it, if istn it would be a useful request like when you need to crop some map, like a graphic help.

Corona version: 1.01.00, Maxsdk version: 2014
Build timestamp: Jun 16 2015 16:48:31
Defines: Wide RGB
Corona bitmap works badly in bump slots. Time benefits are there, but the picture gets blurry and unrecognizable textures. Bump with new map became horrible, I couldn't set it up good

+1
Left - coronabitmap
Right - Standart bitmap
Corona - the best rendering solution!

Kregred and Polymax, how are those bumpmaps made? 1 bitmap or some more complex setup? Screens? Scene?

bump - one bitmap with default settings (CoronaBitmap and standart). and glossy/refl color through standart ColorCorrect.
Coronabitmap loses detail.

I find a very little difference using a jpg prepared to be used as bump (the bw map) and a large difference using the diffuse map as bump (colored map). All parameters are as default.

Btw, Corona 1.01 on max 2015.
My Ducati or a render with Corona.....mmm, hard question!

Actually CoronaBitmap seems to preserve detail across different blurring levels. If you change bitmap blur in standard Max bitmap from 1.0 to 0.1, bump will become LOT stronger, where as with CoronaBitmap, bump amount will remain the same. So you will probably need to compensate for it with bump strength.

in my example blurring level on all bitmaps = default (i.e = 1) and in CoronaBitmap and Standart bitmap.

Yes, i know there is still some difference. Corona does filtering differently to Max's native bitmap. But if you will try blur 0.1, you will see difference will be much bigger ;)

Me too. The overall impression of the image with a CoronaBitmap - no details. Diffusion also loses detail, but I will check.
p.s. It is too early to state, I first perform the test. And tested for complex scenes, rather than simple balls. ;)

Hey, I checked and I can't produce such visible differences between standard and Corona's bmp. Here are my tests. Can you guess which one is which? :) Used different variations of filtering blur, colored and greyscale images, bump and diffuse. Any advices?

Maru, really you can't see any differences between the 2 sphere in the first image? IMHO it seems you use two different picture for bump, the left one is a lot more defined than the right one, and this is probably more evidenced with a glossy material.

You are right, but it is not as apparent as in examples posted above. Btw, Corona bitmap is the left half.
