Title: Exposure disabled when using CameraMod???
Post by: Rimas on 2015-04-16, 13:29:57
Hi!

I need to create some 360 equirectangular pano renders, but I am used to adjusting the exposure on-the-fly with corona tonemapper while rendering. However, even if I change nothing more than the projection on the Corona CameraMod - the exposure gets locked out from the tonemapper. This is inconvenient :(
Any way around this? I'd really appreciate an exposure override toggle in the future version if there's no workaround as this is just a little...annoying.

Thanks!

Bump. Anyone?

Absolutely, the way it is now is the outcome of various discussions and I think this is one case where the current solution should be revised.
At least, the camera modifier should 'listen' to the VFB and be able to inherit all its values so we still can control everything in the VFB but don't necessarily have to when a camera modifier is present.
You'll have to wait for the mods or devs to chime in to discuss this.

Big plus on this.

Is it though ? Seems like a brainchild of single user imho.

The answer will again be: A: "why would you do that ? that's for cammod is for, being stuck in what you set there"
                                        B: Technically not possible. (Funky that Vray 3.1sp has no issue on this front).

I rather don't even use camera mod at all. Worthless.

I didn't say that the current solution was or is the preference for most users, but there was for sure some talk about that when UI was discussed.
In fact, I tend to go with your comment and pick A, and I hate these kind of answers as much as you probably do ;)

I would love this being revised.

You should open request in appropriate section then. It's unlikely that you'll catch developers attention here.

But it doesn't mean the way it currently works is good. There must be a reason and I bet it will get reworked but there are higher priority stuff.

Juraj - I need the equirectangular projection. The current implementation requires me to use the CameraMod. But using it my exposure is locked and I have to do a couple of test renders to nail the exposure (which is a pain once you need to do 10-20 projections in different rooms/etc). I don't mind the camera mod itself, and it's not bad, but the exposure lock is what the topic is about.
Although I do tend to use the VRay camera mostly anyway for other than equirectangulars.

I wonder if it would be possible to save the output from CamMod, then disable CamMod, load saved file into VFB and change exposure. Just an idea for a walkaround, can't test it now. :)

seems plausible, but at the same time how would I check the light strengths and such if I'm rendering blind and hoping to see the exposure later? :)

Why did you quote me ? I agreed with you. I don't use camera mod because I don't need it, but because it currently restricts me.

Let's not get angry, misunderstandings happen :)

I just hope this gets fixed one way or another.
