This is a little tutorial
about how to make a nice render in 3dsm with shadows and
a cool background.
Step 1: Setting up the background
Select the Front
View and under the Create tab – Geometry,
select the Plane button as shown below.
Step 2: Drawing a Plane
After you have selected the Plane button,
draw the plane in the Front view window as shown below.
you can give this plane any color or texture using the Materials
Step 3: Merging a model into the scene
Now merge one of your models into the
scene by using File > Merge,
like in the picture below.
When you have merged the model into the scene you can scale
and rotate it around to get the look you want the scene to
have, like I have done in Picture 4.
Step 4: Setting up the Light and Shadow
Under the Create tab, select Lights (1) and click on the
Omni button (2). In the Omni options make sure you click
the little box next to Cast Shadows (3)
Step 5: Entering the light into the scene
Select the Left Viewport. You will see
a crosshair, click once in the scene to enter the Omni light
into the scene,
as shown below. Please make sure it is a distance away
from the plane and your model. If you want to create larger
shadows, move the Omni up or down.
Step 6: Rendering the scene.
All that is left to do is to render the scene. Go to Rendering
and select Render or press F10. you will see a menu where
you are able to change the size of the picture and to save
the file. Press Render and you are done!
If you want to create a render like your gun is lying on
the floor, use the Arc Rotate button to rotate the whole
scene until you are satisfied with the result.
