Shadows blurred when texture plain introduced



The shadow effect on my model is blurred when i turn on a texture plain.  Is this because of the sun angle, and if so, how can i adjust the sun angle?

    A Textured Plane should not cause reduced overall shadow clarity. You may try the following:

    1. In Options>3D View>Advanced>Driver, try using DirectX11. You will need to close and restart Synchro for this to take effect

    2. In Options>3D View>Advanced>Driver Options, try increasing Anti-aliasing (eg. to 4x) this will increase crispness of diagonal lines

    3. In Options>3D View>Lighting Intensity, you can change the ambient (background) and diffuse (directional) light

    4. Apply a Project Global Light - when applied the sun is stationary, otherwise the shadows depend on the camera angle. Right click in the 3D view and choose Effects>Use Project Global Light. To change the sun angle, hold Ctrl on the keyboard and left click on a corner or edge of the Viewcube (to show the Viewcube, right click in the 3D View and choose Visual Indicators>Axis Indicator)

    5. If you have an Iray license, you may change the rendering settings (inclding Time of Day, Sun Altitude, and Sun Brightness) in 3D View Properties>Raytrace Option

    Thanks for the prompt response.  I have tried all options but with no luck.  I also noted that my text becomes blurred and less refined when i turn on texture plane.  i also noted that the texture plane casts a shadow against the building when i rotate the model vertically.  I have attached a few images to clarify.


    Additionally 'To change the sun angle, hold Ctrl on the keyboard and left click on a corner or edge of the Viewcube' - this didnt work and i could not change sun angle?

    Please send the SP file to for investigation.

    Re: sun angle - you must have Project Global Light enabled before using Ctrl+click to set the sun angle
