[Max] Resolved Bugs / Light size

« on: 2012-11-06, 22:07:54 »

This is what happens when I change spherical light's radius to some higher values. Number in file name is light and sphere radius in cm. Light and sphere radius in max has the same value. Changing it to higher values makes it even more insane - light becomes tiny or invisible.

On those 2 screens with viewport you can clearly see something is wrong, radius was 600cm.

[Max] Resolved Feature Requests / Infinite ground plane?

Would be nice to let ponies run and run and run without falling down!

Work in Progress/Tests / Apartment

« on: 2012-11-03, 22:58:11 »

A scene that will hopefully evolve into something more sophisticated. I always have trouble with starting and finishing stuff, I usually start doing something and give up after a few failures. Maybe this thread will force me to develop this scene. Models are crappy because I made them. Render time 56 minutes.

"displacement" checkbox to globally enable/disable displacement :)

[Max] Resolved Bugs / Displacement + Motion Blur

« on: 2012-10-29, 21:13:05 »

Haven't seen any motion blur tests yet, so I decided to make one.

Uploading two renders - one with displacement on, one with displacement off. Guess which one is which. ;)

The dice are uvw mapped chamfer boxes, the faces with displaced holes in them are single faces. Displacement projected size is set to 1px.

[Max] Resolved Feature Requests / RAM limit

« on: 2012-10-29, 19:37:41 »

I'm not sure if it works this way, but would it be possible to set a memory limit to prevent system freezes when Corona eats up too much RAM? For example when rendering very detailed displacement or having only 4GB of memory like me? :)

[Max] General Discussion / Stupid questions

« on: 2012-10-27, 22:40:24 »

(not sure if this belongs here or to "tutorials and guides")

I'd like to ask some questions that would clarify my vision of how Corona works. I think they might be obvious for those who have more theoretic knowledge about rendering systems, but I'd really like to know this. Maybe other forum users have similar questions so this thread might serve us as noob centre. And yeah, Keymaster, I promise some day I will read whole your Bachelor and Master Thesis. :]

1. When I use HD Cache only, rendered image comes out as a mix of random paint-like splotches all over the scene. I bet that's how it works, pretty much like Light Cache in vray, right? Averaged samples from a certain radius?

SO

What happens when I use Path Tracing + HD Cache? Does it use data collected from HD Cache to speed up path tracing? What's that green-coloured stuff shown in precalculations? Areas that are considered too important and will only use path tracing?

I'd also like to know how certain "thresholds" work. To make the GI calculations more precise and slower, should I lower some parameter, or make it higher. For example:

-Interpolation sensitivity (dir/pos/norm) - I bet making them HIGHER than default values will make HD Cache calculations more precise OR will force it to use Path Tracing in more areas (?).

-Glossy threshold - lowering it will make reflections use less HD Cache and more PT thus making them more precise?

---

Oh, and one "bug" about the Corona Render Settings website ( http://corona-renderer.com/doc/ ). It's neat, but when I scroll down and want to read about some values that are listed at the bottom of the page, the popup frame doesn't fit on screen and I can't see lower part of it. Maybe it's a matter of my browser (Firefox) or screen resolution (1680x1050)?

[Max] Resolved Feature Requests / VFB history + comparison

« on: 2012-10-26, 21:32:32 »

Useful feature: duplicate vfb window with current render to compare with next one. Or you could make a fancy little button to select some region and display previous render inside it.

[Max] Resolved Bugs / Scaling lights

« on: 2012-10-24, 11:12:34 »

I know this is pretty obvious, but look what happens when you scale a spherical light:
Scaling rectangular lights is ok.

Gallery / Toy Car

Few of my previous posts disappeared (including autosave function in feature requests and this one, not fair!) so I re-upload my render.

[Max] Resolved Feature Requests / Photographic exposure controls?

« on: 2012-10-20, 22:12:14 »

Any chance for photographic exposure controls (shutter time, f, ISO, etc) or at least Corona camera object with such settings? It's good for setting up proper light intensity for example when not using procedural sky environment just plain colour with tuned output amount or objects like lamps. Of course this would be connected with real world light units and stuff like lens distortion and glare.

[Max] Resolved Bugs / low res bitmaps in render

« on: 2012-10-19, 21:21:29 »

Here is an example of what I've just experienced. One screen is from max's viewport, one from Corona's VFB, texture is a 1024x1024 JPEG, it's not very high res, but something's wrong as it looks much better in viewport than in final render.

[Max] Resolved Bugs / Some minor stuff I've noticed

« on: 2012-10-19, 12:08:28 »

I've found some tiny bugs (?) that don't much affect workflow but are pretty annoying. Windows7, max2012

When I set Corona as active renderer sometimes the default settings are ok but sometimes some of the values are different - for example "Custom mat. ed" is not checked, max sample intensity is set to 0 instead of 10, in HD cache Precomp step is set to 1 instead of default 10. Anyone else noticed same stuff happening?

Also, in material editor when I am editting a CoronaMtl material pressing TAB key switches cursor to crazy locations instead of next value. Is this intentional?
