Oh cool, I wasn't aware of that. I'll give it a shot, thanks!

[Max] I need help! / Match Physical Camera to Camera Stand-in object
« on: 2018-07-02, 17:07:03 »
Hi,
I've inherited a scene that I need to render with a vray camera, but I don't have vray. Is there a way to convert the 'Camera Stand-in' object to a Physical Camera? It needs to match pixel perfect to the old vray camera.
Thanks in advance

No I haven't tried saving as a .cxr. What's the TL:DR on a .cxr? Is it like vray's .vrimg file? I'll give it a shot later today.
In Corona's VFB post panel Sharpening/Blurring is turned off. I'm using a LUT so I suppose I should turn that off and try it. Bloom/Glare is on and Tone Mapping is on. The image filter is set to Tent.
Good to learn what deep output does in Vray :thumbsup:
To be clear, I haven't messed with any of the material settings on the acrylic. It was dragged in directly from Corona's material library. The light sources are a few corona lights and an hdr pano in the environment slot.

That's interesting about the PS half float. Although I read the only data you'll ever gain with full float over half float is overexposed areas with lots of motion blur, so I can see why they don't bother.
No dice with After Effects, it shows the same yellow pixels.
The hue/sat in 32bit mode does a pretty good job of removing the yellow in Photoshop. In fact, just moving the hue to -85 puts the pixels right back into place.
So not a huge deal, but I wanted to see if there was a fix because the less comping hacks the better.
I wish I had Nuke on this machine to see how that brings it in.

I usually save as a half float .exr. So when this popped up I tried full float .exr as well as .hdr and got the same result.
When you save out an .exr in vray, it has a "deep exr" box to check. What is that and does Corona have that option? Or is that vrays way of saying 'half float or full float'?
edit: wow it gets crazy bringing down the exposure in photoshop (see attached)

Hi,
I'm working on a shot with red acrylic. There are bits in the refraction that look different in Corona's VFB compared to it being opened as a 32-bit .exr in Photoshop.
When I sample the problem area pixels in the VFB it returns negative pixels. So I assume that's the issue. I guess my questions are 1. Why? and 2. If that's the case, is there someway to clamp down the pixels from going negative while keeping all the fidelity in overexposed areas?
The material was taken from Corona's material library.
Thanks in advance. I've been working with Corona for a few months now and really like it!
