carbon scatter does not support the renderer you selected

[Rex Dougherty]

I am using 3ds Max 2011. I select Paint Ecosystem from the Carbon Scatter menu and open the Carbon Scatter painter dialog. When I press Add under the EcoSystem Population window to add items I get a dialog box that says that "carbon scatter does not support the renderer you selected". I don't believe I have selected any special renderer. What's the problem????

The problem is...ScanLine render engine! Set MentalRay or VRay render
