Title: corona bitmap loader
Post by: Christa Noel on 2015-06-10, 10:19:39
hi all,
just like allessandro said, it seems faster than max default when I first use it. cool!
with latest daily build I used a spherical hdri as environment lighting. I set the RGB level to 10, then when I close and reopen it, i see the value is still 10 but the light is revert back to default value 1. I have to reenter the value again to make it work.
it doesn't occurs to any value inside parameter rollout, only rgb level, output amount & invert.. RGB offset & colormap is ok.
and a question, does corona bitmap loader have a spinner for "inverse gamma" just like vrayhdri?

It's already known issue. The problem is that color mapping settings in output rollout do not get initialized before UI is drawn. Robin is working on it.

As for the inverse gamma thing. Why would you want that? Ever since Max 2014, 3ds Max correctly handles gamma based on image format.

I think he means something like color correction setting, for example you put 0,8 to boost contrast. Not sure but maybe it is the same as rgb offset in output tab?

this is simply not gonna happen ;)

There are already enough output settings, and if not, we can add more, but NOT gamma.

I can't reproduce it with the 09.06 build. Could it be Max version-specific?

great news guys.. :) yes, I need to boost the image's contrast. rgb offset gives the different result than inverse gamma.

this should be fixed now

checked today and couldn't reproduce again, so I bet it's fixed
