Hi,

I was trying to run multidevice example from chai3d 3.1.1. I'm getting a runtime error and compiler always pointing at

cTexture2d.cpp 
at ---> glActivetexture(m_textureUnit)

CHAI3D uses the OpenGL framework to perform 3D graphic rendering. Under the Linux and Mac OS X operating systems, OpenGL drivers are provided by default. If you are using Windows and have installed the operating system directly from a Microsoft Windows Installation CD or DVD, you will need to update your graphic drivers by downloading a fresh copy from the website of your graphics card manufacturer.

If you card is an ATI or an NVIDIA model, you may find a link to their website here:

• NVIDIA: www.nvidia.com
• ATI: www.amd.com

I did updated OpenGL and graphics driver but experiencing the same issue, I'm wondering by any chance this error is due to OS incompatibility?. This is happening only when I run my application on 32bit Win7!?

Thank you for the note. We will further investigate the problem.

Thank you!. Lately I found runtime error is particularly due to 2D objects; basically I'm getting an exception access violation (0xC0000005) during runtime. And always pointing as mentioned before at CTexture2d.cpp

glActiveTexture(m_textureUnit);

Are you observing this problem with the 32-bit version of Windows, or the 64-bit?
What 2D object are you exactly disabling/enabling?
