[Rio] Error while opening form

[LefjuCabro]

Hello GLScene's community,

I installed GLscene v.1.8 with Delphi Rio 10.3.

I have an error that looks like this (according to translation): "Error while creating form: range check error".

I can modify source code but I can't open design form. The build of my application if fine, this form works perfectly during execution.

At design time, this form contains:
- 4 x TGLScene
- 4x TGLSceneViewer
- 13x TGLDummyCube
- 4x TGLCamera
- 12x TGLArrowLine
- 4x TGLWindowsBitmapFont

I don't have this problem when opening this form with Delphi Berlin 10.1.

Does anybody have an idea to solve this problem ? I don't want to delete all GL-controls and design it again.

Regards

Hi
perhaps an error in the dfm.
The question is on wich object "range check error" appear ?
Try this : make a copy of your project with just DFM, DPR, PAS, and DPROJ files
Clears all other files from Berlin 10.1

Hi BeanzMaster,

Thanks for your answer.

I also think it's an error in DFM, I don't know which object raises the error.

In Rio, I close all projects and open only my form (PAS+DFM), the problem still appears. ;-(

Can you send me your DFM+PAS i'll take a look. I send my private mail by mp

BeanzMaster checked my files and gave me a solution and explanation:

The GLSceneViewer.Buffer.AccumBufferBits property, the 2048 value is way too big. This value is expressed in bits and not in bytes (2048 = 256 bits). You can not have such precision. So to fix the problem changes the value 2048 of Buffer.AccumBufferBits in the DFM by 16 which is largely sufficient in my opinion. The maximum accuracy is 128bits

It solved my problem

Thank you
