Corona Bitmap shader yes or not?

[masterzone]

Reading some topics here about using or not the Corona Bitmap Shader, I tried to convert a scene created without bitmap shader and changed all scene materials with Corona Bitmap...
I got the same render times...what do you think about?

Any tips or suggestions?

I think the issue is only a problem if it doesn't work, renders much slower or crashes a scene. The Corona Bitmap has more features, but it does cause some people some problems.

The biggest one for me was collecting a scene to be used on other system or Team Render (render form too) that used materials that had their texture maps stored in the Asset Manager. Those file names get changed to some random set of numbers in the collected tex folder and of course breaks the link. If you have a large scene with hundreds of materials, this is a massive problem. Even knowing it ahead of time and trying to change to C4D bitmaps in the material can also be a show stopper if you have lots of materials.

I don't think any major render speed differences are expected. Perhaps if you use the Nearest filtering method?

Corona Bitmaps should generally use less RAM than the native C4D/Max bitmaps. You can learn more here: https://support.chaos.com/hc/en-us/articles/9813408385937-Out-of-core-Rendering-for-textures-C4D

We also have a new way of handling bump/normal mapping in Corona 11 and it works only with Corona Bitmaps - https://support.chaos.com/hc/en-us/articles/19161682524305-New-Bump-Normal-filtering-in-Corona-11

Here is also our general Corona Bitmap documentation - https://docs.chaos.com/display/CRC4D/Corona+Bitmap+Shader

So you can totally use C4D Bitmaps, but Corona Bitmap is designed to work optimally with Corona.

ah ok thanks very interesting about memory usage....
