Rendering Entities

Chris, In the documentation, it says "Power Render does not include an entity list. You must explicitly tell what entities to render and when." If I am reading this correctly, does it mean that if I have a mesh at a certain location in a level, it''s up to me to decide if it is visible (no walls/other meshes and within view frustrum) and based on that determination, render it or not. Is this correct? One other question unrelated. Portals. Can I create a 3ds object and instead of using a texture, project an image from a different camera onto that object? Example: I have a simple cube 3ds object (converted to pr4 object) and a camera at a certain position in the level. Can I render the view from the camera onto the cube? Sort of like a video monitor. Thanks and good job on the engine. -Mark
