Shadow Issues

Elith2

Hey guys, not sure exactly what the problem is, it might be to do with LODs but as i said i'm not sure. But yeah it seems to be the further i pull back from my model the weirder my shadows become, anyone any idea if there is a fix for this, or if i am just be catastrophically dense. Either way a solution would be much appreciated. Here are some images to help you see my issue.

I managed to solve the problem with a dominantdirectional moveable opposed to a basic dominant directional, its not exactly a fix, but its solved the issue for now. If anyone has anyideas why that seems to happen though it would be appreciated none the less

Was your stuff imported at the standard UDK measurement/scale?

udk seems to have started streaming shadowmaps which might be causing this problem. there's a couple of threads talking about it on here somewhere i think. the workaround i've been using is to use the override shadowmap resolution option in the mesh properties but that has to be done per actor. using a moveable light just forces the lights to be dynamic doesn't it?

@TDub

It wasn't no i only used a UDK base mesh character as a rough size reference, so it wasnt built to any specific grid measurments.

@tharle

And yeah i believe it does just cause them to become dynamic shadows using a moveable light, but yeah that seems to have cleared it up but as i said it's not really a fix as its a more expensive light to use.

I seen a few people mention the shadow map resolution thing but it didn't seem to correct the problem. For what im doing at the moment its fine, but in future i need to find a correct way of doing it.

Not everyone seems to get the issue, so im wondering if im just doing it wrong hah.

You should try adujsting the the "whole scene dynamic radius". Which is a parameter in the lightcomponent of your Dominant light. This controls where the shadows get LOD'd

Hey sorry for the late reply. Thanks for the advice man, it's something i will need to try out.

Thanks again for all the help and advice guys
