Possible to improve rendering of sculpties from larger distance?

Hello,

Short question:

Is it possible to tweak some under the hood setting to increase the maximum distance where sculpties will still be rendered perfectly? I need a temporary workaround so I can take pictures from a few meters distance from my sculpties where they still look good. Close up pictures is not an option, I need to photograph a cupboard containing various detailed pottery sculpties.

Thanks in advance

Saw a thread recommending changing setting:
Advanced>Debug>RenderVolumeLODFactor - set to 5

/327/72/290302/1.html

Hope that helps.

This helped majorly!

Thanks for saving the day ;)

Cool. Thanks, Drifter. I didn't know about that.

Yw, Chosen.
It's fortunate we can pick up on these things from each other as LL don't seem to be too hot on the documentation. :(

I guess it depends if it is how you want your viewer to show them or everyone's...

Changing the LoD level in your viewer affects you and your render speed.

When the sculpty is built the builder can affect LoD. The first chairs I built have horrible LoD affects. A later table looks the same no matter how far away you are. Well... inside a building.

I have the same issue... i've only recently been learning about how to improve my LOD for my sculpts and my sculpts are looking much better at the different levels of LOD. The solution proposed above may help me (i haven't tried yet) but the problem with that, is I will be thinking my sculpts look great while everybody else is seeing them degraded. My sculpts right now pass through different levels of LOD without much quality loss , but then I hit that last level of LOD where the sculpt completely falls apart and i'm not even that far away from it. I've seen other people's work .. some chairs, and other objects.. where I am able to zoom way out before they finally hit that final level. So I'd really like to know, what is the trick to making the distances at which my sculpt degrade longer?

with blender you can go these ways:

- You can simulate the LOD by using Multires (effectively multires IS LOD) and you can effectively shape your model using the LOD level corresponding to the lowest resolution. You sculptie doesn't look great on that level, but at least you can possibly find a reasonable first shape.

Then you go to the next LOD level and there you optimise your shape for that level. Proceed until you got to the highest resolution available.

If you work like this, your sculpties typically have a high degree of LOD invariance.

- Another more recent way to go is to use subsurf which more or less calculates perfect LOD-invariance for you and keeps it all right during the whole shaping process. Just keep with your subsurf model until you like what you have, then bake it and it is most likely LOD-invariant.

- If you know exactly, how LOD works, you can tweek your sculpties further on the vertex level. A few months ago i have shown how to create a perfect LOD-invariant yet high precise arch bow in one of the machinimatrix tutorials. maybe you like to watch that one too ;-)

Good luck
