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

    Hello, and right now I have the same problem with my project. Do you have any additional information / solutions on these days?

    This may also be related to having a model very far away from the origin. You may check using the 4D Review>3D Notations>Footnote or Comment tool to determine the coordinates of a point in the model. If it is far from zero (e.g. on the order of miles or kilometers) then you may try moving the model to (0,0,0) on import or after import (but before assignment to tasks) via 3D Properties>Translate
