Great stuff Gabriel, this will save me a lot of hassle on current projects!
Really appreciated, many thanks!

That's interesting Pokoy as I have been getting some strange anomalies in 2015 and torn edges from perfect origination files, helps explain a lot!

General CG Discussion / Re: .step files into 3d Max HEEEEEELP

Hi Monster,

The solution is to use Rhino and export geometry as .obj using the detailed mesh control option.
In the detailed mesh options you can limit edge length.
Limit the edge length (baring in mind relative object scale) and test using the preview option to eliminate long, elongated polygons which are the culprits.
Bare in mind the default 0 edge length means it is deactivated and allowing the potential for elongated polys.
Since using this approach and getting to know the mesh settings controls I have eliminated a whole host of import issues in Max.
Optimised obj meshes will also massively reduce file sizes in comparison to body objects, so win win.

Thanks for the tutorial, it is working well for the most part.
I have one issue I hope someone can help me with.
On some geometry the UVW map when scaled up creates strange artifacts (normals issue I assume ?).
How can I deal with this, the geometry is a Rhino originated obj conversion from NURBS.

[Max] I need help! / Re: Corona Shadow Catcher Material - Reflection question

« on: 2015-05-20, 14:41:49 »

I had similar issues, except I wanted a pure shadow catcher without the GI input of the backplate for a product shot.
I found the solution was to use the Rayswitch material and  the run shadow catcher through it to deactivate individual passes :)

Ah speltospel, just realised who you are, followed your work for some time!
Cool to see you on here and using Corona, great stuff!

[Max] I need help! / Re: Blurring Bercon Noise

For future reference I found the issue, appears that filtering does not work when using Hetero Terrain Noise Fractal.

Tried another Bercon map and the filtering now works fine, really strange!

Thanks Headoff!

Hi Headoff,

Thanks for the help, my first thought was also the filter strength, however it did not seem to make any difference on my side.
Is there something I am missing? Attached my test.

Cheers

Can not work out how to blur a Bercon noise map in the same way you can blur a standard noise map, any ideas appreciated!

Experienced the same bug in two different scenes, both crashed when moving the texture light with IR active.

I have uploaded the dump file:-

and the version was licensed 1.00.02.

Cheers.

Looks bloody great! Just like the local bricks in the area I grew up in.

Indeed, MOI has a very exotic UI ;) But when you get used to it, you soon realize that you can get incredible results in the shortest amount of time. I too use it in everyday production, mostly as a chamfering / filleting tool.

The one particular issue with it, is when your input files get too large - like 100 mb or so. Then it takes a significant amount of time to open them, although eventually they open up successfully. Never tried rhino though, a lot of people told me that it's a great tool.

Now to the normals issue. For me the same thing, NDA, can't show too much here unfortunately.
But i digged up one comparison. On the left is Alpha 0.72, with the broken normals issue. 1.00.01 produced the same result. Yesterday we finally bought our licenses, I will investigate further. Still, it's definetely a STEP-file issue, i rendered other PowerTranslator imports with Alpha 0.72 without any issues. Litttle spoiler: Vray renders the geometry without any issues ;). I am currently migrating my whole CAD animation workflow to Corona, it simply rocks - unbeatable in terms of tweaking time <> coffee breaks :)

Hi Gabriel,

Looks like the same issue I had here and I get it from either Solidworks, Rhino or Alias geometry:-

https://forum.corona-renderer.com/index.php/topic,6170.0.html

It is the bug/poly conversion issue that Ondra had stated.

The problem is two fold.
As Ondra first pointed out to me, the problem areas are where the conversion creates extremely elongated polys (seems always to be when resolving trim edges) so I believe the problem may be resolved with better mesh conversion.
But yes, somehow other software (and as you flagged the Alpha 0.6 version) is managing to resolve these nasty conversions at render time.

Inspired by ignicapillus's comment on Rhino's advanced mesh settings I went back and experimented, seem to have resolved some of my problem geometry, so thanks!
