Hi,

 

>> I want to avoid shadows of point light and distance light

Which version of AutoCAD?

For newer AutoCAD versions you can't avoid shadows (I guess because of realism)

Hi,

 

>> falls on image background from distance light

What type of geometry is your background? If it's really just a background image and no geometry, no shadow should show up there.

Can you please run command _ETRANSMIT (to pack all together, drawing + images) and upload the file here ... that gives us the option to look into it. Please also let us know the version of AutoCAD you are using.

good morning,

 

Please find attached etransmit and also rendered walkthrough. Shadow is "really" disturbing quality.

I use Autocad 2017.

 

Thanks

Hi,

 

you have seen these 2 dialogs?

 

Both are not good to have with your scene and especially the heavy number of lights you have.

Where does the dwg-file come from?

Have you set the lights or were they already defined when you started with AutoCAD and this file?

 

If you don't want to have a shadow for the background, then please don't use geometry for your background. Geometry objects receives shadows. Instead use the environment option to show a background as shown here:

thanks a lot, this was the output from tekla model, how to place the image exactly in the x,y,z co-ordinates. From the background option that will only stretch or tile etc.

Hi,

 

placing a background like an image is not possible (not with AutoCAD afaik), but you can edit the image so it fits to the space/to fill the background :cara_guiñando_un_ojo:
