[Max] I need help! / Opactiy mapping misery

« on: 2015-01-08, 18:28:01 »

Hey,
I have many decals in the form of either dirt overlays, Pictures or signs on walls, imported as TGA's with a an alpha channel.
Alpha works in Vray, Scanline but not corona.
I tried every possible combination of checkboxes for Alpha interpretation and threw in many Corona textures in between, nothing seems to interpret alpha correctly.
Am I missing something here?
With settings that works for other renderes, Corona seems to interpret Rgb as alpha, although I dont have it chosen in the Bitmap setting (image 1). If set RGB mode to ALPHA as gray its works, but obviously without RGB color (image 2).
I can't possibly export a second bitmap with gray values for Alpha for 300+ textures (without going mad, that is)
I tired all workarounds mentioned here: https://forum.corona-renderer.com/index.php?topic=1017.0

will give cookies for help

[Max] Feature Requests / Re: The most wanted feature?

« on: 2014-12-15, 23:05:45 »

vrayblend mtl please?! does anyone know if the next versions will come with this feature? vray dirt are welcome to! =D

No offense, but this makes me doubt you actually used corona :|
Corona supports maxes own Blendmaterial [100% same as vrayBlendmtl exept coats], if you are looking for coats like from the vray mtl you can do so by daisy chaining blends in the SlateMaterial Editor easily.
What do you want from vray dirt, if its AO, then corona does support that aswell for quite some time now.
There is a CoronaAO texture already there. If you need an AO pass, add corona's "CTexmap" as a render element and apply the CoronaAO texture. Then in Actions press render elements and you will get your AO pass.

Lastly, if you are into optimizing:
Need AO? Duplicate final scene,  delete all glass material objects and render with Mentalray's GPU ambient occlusion. (coronas is kinda quirky still)
Need DOF? Render Z-depth pass, and your image in 32-bit. Just like the real thing only 100x faster.
Need MoBlur? Start spamming Keymaster to implement a velocitiy pass already, or duplicate scene and render a velocity pass in scanline.  Just like the real thing only 100x faster.

Why is it so

To clearify, Corona has its own Matte/Shadow material, the so called shadow catcher.
Matte/Shadow is only supported by scanline and mental ray.

[Max] I need help! / Re: Lines visiable in render

Miss connected DVI pins are known to produce either Blue dots or colored (and I suppose grey) lines in a 0-128 brightness range.

Blue dots on a 40 grey used to worry me sick two years ago, having thought I broke my graphicscard memory by an overclock two years ago, until I discovered it was the bloddy, supposedly artifact free, digital cable of the 21st century ;]

[Max] Resolved Feature Requests / Add Passes to Sequences

« on: 2014-12-09, 22:46:25 »

Hey,
doing mostly vfx I see corona currently as not feature rich enough.
However, looking at the resume render/dump option and Cinema4D's (which I hate) direct implemenation into AfterEffects and its ability to improve a render, while/after you are compositing,
I'd love to see the following added:
Let's say you rendered  a 100 frame 25 pass/frame animation and exported it as openEXR's.
There should be an option to add another 100 passes per frame for a given sequence, without the need to reapply all rendersettings afterwards, meaning the inclusion of a potential new *.corona file for render settings.
That would make corona a bunch more interesting :]
