CA House in Angola.
After the finished colour renders I tryed a different version with some filters from Nix Silver Efex.
It turned out "different" but somehow I enjoy it like this...

[Max] I need help! / PNG with alpha channel - Compositing problem

« on: 2014-07-25, 12:57:00 »

Hi

My usual workflow in vray is to save the rendered image to png with alpha channel. This makes it easy to open in photoshop and have a transparent background to apply a sky. In vray I renderd the final image with a black background so that in photoshop I could get a perfect edge by removing the premultiplied pixels with remove black matte.

In corona this workflow doesn't work as you can see by the attached images. Remove black matte leaves a white edge around the image.
What is the best workflow for this kind of situation in corona?

Thank you

[Max] I need help! / Displacement not working correctly

« on: 2014-07-25, 01:25:13 »

When I apply displacement to the pavement I get this result. See picture.
The map is a grayscale from black to white. Black for 0 displacement, white for 2cm displacement (min level 0, max level 2cm).
Tried to change the displacement screen size to lower values (0,05px) but nothing changes.

Any ideas?

[Max] I need help! / Can't get rid of fireflies

« on: 2014-07-16, 15:38:52 »

Trying to make a simple interior but I can't get rid of these annoying fireflies...
I know there are some topics on the subject, I've read a few but nothing seems to help...
I mean, I think these are fireflies, or is it normal to have such strong noise and it will go away with more passes. This current image has 45 passes.
I tried with override material and I continue getting fireflies. Does this mean it could be a geometry problem? What kid of geometry problem could cause this?
I'm using corona lights.
Corona with all default settings.

Ideas anyone?

[Max] I need help! / Corona Light renders black

« on: 2014-07-07, 22:15:38 »

My rectangular corona lights are rendering black. They emmit light. The spherical ones render fine.
If I turn off occlude other lights they disappear but continue to emit.

How can this be solved?

[Max] I need help! / Displacement - can't get it to work properly

« on: 2014-07-06, 22:58:12 »

If there is one thing I never got to understand is corona displacement. All my efforts have been in vain... can someone help me?
I set a map in the displacement slot and then play with the displacement settings in "screen size" and "world size" and all I get is results like the one you can see.
I'm trying to make a simple stone wall with just a little bit of displacement and the resut is this:

[Scatter] I need help! / Corona Scatter

« on: 2014-07-06, 12:48:24 »

Hi

I'm trying to make grass on a plane with corona scatter. The problem is the grass is on the wrong side of the plane, so "growing" upside down. The normals are correct, and were working well with multiscatter.

Any advice?

[Max] I need help! / Corona proxy crashing - SOLVED

« on: 2014-07-04, 14:58:43 »

Hi

I need to create a parking lot with aproximately 50 cars. The models I have are evermotion HD cars. When I try to convert them to Corona proxy max crashes. Are they too heavy for Corona? If this fails I will have to render with Vray, but I was hoping I could do it with Corona. I'm using Corona V7 and 3ds Max 2014 x64.

Thank you

[Max] Resolved Bugs / White Renders - help

« on: 2014-06-30, 18:33:11 »

Hi

Corona usually works fine. But sometimes, and I have no idea why, it renders the image completly white. When this happens the passes increase at extreme speed (like 100 passes per second). So something is going wrong.

The only way I found fixes it is opening an existing scene (a working one) and merge the other scene into it. It's like the original scene got corrupted or something like that.

Any ideas?

A few quick renders I made recently for a client.
Some imagens didn't render long enough, but overall I like the results I'm getting with corona.
I now realise I added too much sharpness, which contributed to make the grain more noticeable.

What do you think? Comments are welcome.

[Max] General Discussion / Problem with Mighty Tiles

« on: 2014-05-16, 19:12:37 »

I'm rendering a scene with mighty tiles plugin. It works fine except for the displacement. When I insert mighy tiles material in displacement slot the geometry goes crazy...
Am I doing something wrong or is it a current limitation of corona? Seems the map is too strong but when I assign an output map and decrease the output amount to 0,001 I still get smaller diplacement but crazy geometry...
