Hi Martin,


> but in the full render that Modo uses then the creasing shows ...

That's looking like a different kind of rendering artifact called "self shadowing" that can happen with raytraced shadows. It's probably possible to avoid it by adjusting some kind of shadow bias factor. Or you might try scaling your object up or down to match what Modo's built in shadow ray bias distance setting expects for objects to be generally sized at.

It's also possible that making a more regularly diced up mesh instead of one with long skinny triangles in it would help somewhat to avoid that kind of artifact as well, but I'd think that adjusting the bias render setting should do it, look for a setting like "self shadowing bias factor" or something along those lines - it probably needs to be bumped up.

You won't see any artifacts from raytraced shadows in the realtime modeling view because it's not doing shadows there.

I'd pretty much always recommend the reverse of this - just in general a more finely diced mesh will help avoid various kinds of rendering artifacts.

Some render engines may have other various settings that affect the render and the settings can be size dependent, I think that's what you're seeing with Modo there. To solve those you have to adjust the rendering settings, not really do anything different to the mesh itself.

Keyshot probably does a better job of automatically managing this particular kind of render setting for you, probably in Modo it's a setting that needs to be manually adjusted to match the size of the objects that are being rendered.

Keyshot is sort of overall focused on trying to make rendering more of a single push-button thing without needing a lot of settings to adjust in order to tune things as is often the case with most renderers.

Keyshot or SimLab Composer who is more affordable( it's has the same Luxion render engine inside)
all is made for an easy use! :)

Actually Pilou, Simlab now use their own developed render engine technology in V2014 not Luxion.

Ah thx for the info!
Luckily i have only spoken of that only in this forum! :)

Guys,

here is my next question to this. Didn´t want to open a new thread, or should i ?

How can i "fillet" smoothen the sharp edges of the "stripes"

If i try fillet with all Option G1 - G3, circle and so on, no smoothening of the sharp edges appear..

Any solution ?

Thanks in advance !

Hi sosodef, what fillet radius are you trying to use? It looks like probably only a pretty small radius will fit in the space you've got there. Try going down in increments of 1/10 like try a radius of 0.1 or 0.01 and see if that produces a fillet. If it does then it means your original radius value was just too big to fit in some of the corner areas of your shape.

If you need more help please post the 3DM model file that you're trying to fillet, that will make it possible to take a look at your geometry and maybe give some better tips.

Hey Michael,

it is about the same model which i uploaded before in this Thread. It is about the "weird lines" object.

In this file you can the "stripes" right, which are boolean cutted... I tried 0.1 mm and lower... unfortunately i could get no any results.

Is it possbile, that i just cant see the "filet" if i choose 0.01 but in fact it is "there" ?? If yes, isn´t 0.01 mm filet also pretty close to a really sharp edge ?

Thank you in advance.

Hi sosodef,

Ok, but you never attached the 3DM file for this model, as far as I can see you only attached the OBJ file. I can't try to fillet the OBJ file, I need your 3DM model file in order to look at any fillet problems.


> If yes, isn´t 0.01 mm filet also pretty close to a really sharp edge ?

It depends on the particular scale of the particular model.

It's hard to give you any good information without being able to examine the 3DM model file that you're having problems with. Please post the 3DM model file (not just the meshed OBJ one) and that would help me to be able to take a look at what you've got and try to give you some tips.
