3 months ago This is still an issue in Godot 4.3. POINT_SIZE appears to be ingored when generating shadow. It acts as if POINT_SIZE is always default size no matter what yo uset it as.
Godot version
3.3.2 latest official release
System information
Windows 10, GLES3, GTX 1650 Super
Issue description
Point Mesh shadow ignores POINT_SIZE when a Viewport Node with a Camera child is present in the scene and the Viewport has Render Mode set to Always. Switching to render back to When Visible fixes this issue.
EDIT: I believe this may in fact be part of a larger issue where point mesh shadows are scale relative viewport_size and not just POINT_SIZE and on very small viewports the point shadow is much smaller than the point itself. You can in fact see this triggered by making window really tiny and you will see that the shadow becomes a bunch of points. You can also trigger this by setting a low viewport 320x200 and set your Stretch Mode to Viewport to start the game in really low rez.
Steps to reproduce
Is quite difficult to reproduce this issue as it requires very specific conditions.
Instead please have a look at the test case below.
However just for sake of completeness it seems to require: point mesh with shadows enabled, an Omni Light with shadow casting enabled, a surface to cast shadows on, a Viewport with a Camera attached to it as well as the Viewport has to be set to Render Mode Always.
Minimal reproduction project
TestPointMeshShadow.zip
At the top of the project there is a Viewport with a Camera attached to it. Camera must stay attached to Viewport to trigger this issue. When changing Viewport Render Mode to Always this issue will occur.
RenderMode: Always
RenderMode: When Visible
