WorldShadows problem & fix

[APEXnow]

Hi everyone,

I've recently purchased PB and began playing around with the Engine3D library. All great, until I started playing around with getting the Shadows working. I have discovered that the WorldShadows function, crashes the application (Windows 11 btw) straight away. I couldn't figure out what was going on until I added the following line into the code before calling 'Parse3DScripts':

Add3DArchive(#PB_Compiler_Home + "examples/3d/Data/Main", #PB_3DArchive_FileSystem)
...
...
Parse3DScripts()
...
WorldShadows(#PB_Shadow_Additive) ; Use which ever option you desire here


I was unaware that there is a 'Shadow.material' file in here that appears to be required to make the shadow stuff work. There may be additional files as well. You may want to copy the files located in the Main folder, to your own application's source folder and adjust the path accordingly if you are using your own materials etc.

I hope this helps people who came across this issue.

On the other hand you could read the very first sentence of the help of Parse3DScripts:

Parses all the .materials OGRE scripts found in the paths set with Add3DArchive().

https://www.purebasic.com/documentation ... ripts.html
...so I guess people are already aware of this.

I'm just trying to help! No need for the sarcasm. This information would never have been known if I wasn't using Scripts.

I don't think it was offending, please don't take it seriously. Anyway, welcome to the forums, and feel free if you have any questions, or got something to show/tell. (the feature you pointed out is not so obvious, others also ran into it (including me))

I agree it's not obvious, I will add a note in the doc.

shadow management is, in my opinion, the biggest weakness of 3d PureBasic (along with physics)
especially since PB 6.20
I advise you to leave this aside for the moment.

PB 6.30 should correct this problem

in the meantime, I've included in PB 6.21 the ability to manage "modern" shadows
it's a bit of a DIY job, but it's much better

Sounds good. I think the community can manage this until 6.30

I appreciate the heads up and I'll check for an update. I'm currently on 6.20 still.

Sorry a question about shadows. When use texture shadows, If I have understood correctly, need add a layer to the material for the shadow?. I read this in ogre forum.

At the moment PB handles that internally as far as I can tell. It should have a lot of secret shennanigans like depth camera and depthmap texture etc, but it's hidden.
The 3d example Light.pb uses texture shadows.
