Hi guys, Just a quick question… Is it good practice to load all bitmaps within a Corona bitmap shader? Until now I have been loading bitmaps directly in to the diffuse texture slot. I was having a play with Tone Map Control and couldn’t get it to function properly. With all the exposure, LUT & t…

I would like to know about this too.

Me too. But I would guess by the amounts of replies, that the Corona Bitmap is not THAT important.

Yeah this topic has not really set the world on fire… I’ve not been using it so far and haven’t seen a reason for it other than in conjunction with the tone map control. However, it must be there for a reason??

Afaik in 3ds Max it should potentially speed up the render times - by a very small amount. Should be similar in C4D. Other than that the Corona bitmap should offer you some settings that the native loader doesn’t. In 3ds Max it has a few extra options (and a few missing) than the original UI but tha…

I think CoronaBitmap will be more important when Corona materials become cross-platform. Similarly to nkilar, i rarely use CBitmaps too, except for loading HDRIs, where it has noticeable speed advantage and superior projection modes.

This may also offer some insight: https://coronarenderer.freshdesk.com/support/solutions/articles/12000033420-what-is-the-difference-between-corona-bitmap-and-3ds-max-bitmap-node-

Somewhere around here I read that it significantly speeds up rendering with textures that use Opacity.

Found the link: https://forum.corona-renderer.com/ Opacity channel sends render times through the roof #msg99347
