Hi,

I have a new notebook and I cannot add/edit a bitmap component, because an access violation occurs. I now its has something to do with the Intel Opengl drivers.

I apreciate any fix/workaround.

Thanks in advance!!!

Specs:
Intel CoreDuo
2Mb Ram
windows 7 Pro

Mobile Intel 4 Series
GMA 4500MHD
128Mb
Drivers 8.15.10.2086 (20/02/2010).

Steps to reproduce the error:
Open ZGE.
New project
Select Content
Add a Bitmap Component.

I see in the log-window that the card supports shaders and 8 multitextures so it seems capable enough for a Intel-GPU.

1. If you open a zgeproj-file with textures (like zpong) does it work when you run it in the designer?

2. Is the error message the same when you click on a existing bitmap with bitmapproducers?

Hi Ville,

Zpong runs perfectly on the designer! And every game with bitmaps/textures. It is only when you access the component at the designer.

The error is Access violation at address 1052F255 in module 'ig4icd43.dll'. Read at address 0000000. When I click over the bitmap component, the error appears and I can see the graph but not the preview.

It has something to do with the preview of the bitmap. And its seems its Intel opengl drivers.

I cannot choose the notebook, It was assigned to me.

Sorry to bother you guys.

But I cannot develop since yesterday!!!

(I know I'm a ZGE addict )

I'm not sure what's wrong here and I need to examine it more closely and upload debug version for you to test. Meanwhile I can think of a temporary workaround:

- After the error message has appeared, click the "Hide preview" check box to disable the preview window. That should get rid of the error message.
- To see the texture you are editing, click on a Model that use the texture and "Lock preview" to that component (Ctrl+L). Now you can still edit your bitmap and see realtime previews.

Ok, I'll wait for the debug version.

I cannot click on the "hide preview" because the error window is blocking the focus and I cannot select the checkbox.

Thanks!

Hi Lupo,

What about the following workaround?

- Create Model
- Lock on Model
- Create Bitmap
- Create Material
- Add MaterialTexture to Material ( set to Bitmap )
- Add UseMaterial to OnRender of Model ( set to Material )
- Add RenderSprite to OnRender of Model

Then you should be able to edit the Bitmap ( and see the results ) without problems? Still s*cks though, hopefully the problem will be resolved soon ~

When you click OK on the error dialog you should be able to click the checkbox. Or is it constantly reappearing?

Do you get the same error message when creating a Mesh? There is a preview window there too.

@Ville

It's probably a error generated in the preview / render loop, so as soon as you deal with the popup the error is generated again Perhaps it would be possible to automatically stop any active preview when such a error is thrown?

Yeah, I know all about that.

(thanks for the interest.)

Yep, exactly it loops forever.
Meshes work perfect!

I can't see why it works with a mesh and fails with a empty bitmap *scratches head*

Try this:

It will probably still crash but you should be able to turn of preview with the check box after the first error message. Then switch it on again after a while to see if it always fails.

Sorry the meshes preview is not working, I got confused, the Model preview is wokring and the application preview is working too.

I'm downloading this version and trying...

Well, I tried this version.

The error messages does not loop it just appears once per component. I can click the "Hide preview" checkbox. But when I clicked over another component the error appears, despite the checkbox is checked.

What is the difference between the mesh preview and the model preview? how they create the contexts ?

Thanks in advance

The preview window for bitmaps and the main preview window shares the OpenGL context but they have different Win32 handle and device context, so there is probably a glitch when the handle changes. I tried to rewrite the OpenGL panel component and simplify it to the bare essentials (the original code was a component I found on the web and had lots of features not needed for ZGE).

Another update today: http://www.zgameeditor.org/files/ZGameEditor_beta.zip

Any difference?
