Shadow Bug?

[DudeAwesome]

I create some kind of 3D menu for my game and started with a prototype to test if it works. I created a background and some buttons and added some models + a animated character.

 

 

if my cam is in front of the buttons (orange cuboids) shadows are ok but still ugly (MSAA 8x @ 1600x900)

how can I increase the quality of the shadows?

if I pull the camera a little bit to the right it looks like this and drops strange shadows

first I thought it is because my lightning source but I changed the position from my light, nothing changed

 

 

 

I also noticed that the camera behavior is a little bit strange when you select a camera in the perspective window and use WASD to move the camera from the editor itsself. it looks like the blue camera lines have a wrong behavior.

I got that problems already.

Mainly from geometry problems :when they are boxes penetrating a big one , shadows or lights can do such glitches.

 

You could try to use simple models to see if it makes a difference ?

I made sam wall for you in FBX format , ready to import and test

mhmm I imported your model, resized it and added the orange grid in the model editor. (the UV maps are pretty ****ty btw. the lighting is strange wrong even without no material) but the material is not drawn. its just a small touch in orange.

It looks like that might just be a normal artifact from where directional light stages change. The further stages have less accuracy and will have more pronounced artifacts like that. This is just a normal thing that happens in any game using cascaded shadow maps:

 

Fun fact: early in the development of Leadwerks 2 I experimented with parallel-split shadow maps and dual paraboloid shadow maps, but both had horrible glitches that could not be overcome, due to their fundamental design.

I tried dual paraboloid env reflection, it reflects in realtime but it looks wierd and streched.

Give us back Lightmap import for static geometry

but the problem only exists when I have my camera at position B. Is this a bug or I doing something wrong, its just a simple scene with no fancy stuff and I´m not even able to do such anything?

 

you also noticed the strange camera behavior when you click the camera in the editor (in perspective view) and move around with WASD. the "view" (blue lines) moving strange.
