Title: RedSDK - The easiest way how light up the scene
Post by: Majo on March 16, 2019, 06:52:43 AM
Hi all,

I prepare quick tip tutorial how you can easy light up the scene with RedSDK.
Hope you help!

Attention! Be careful not to have any lights in the scene!

Steps:
1. Menu -> File-> New -> New From Scratch

2. Draw simple scene with 3D Object/s

3. Draw the floor -> I use mostly 3D Mesh with nodes in x-2 and Y-2. This object will serve for catching the shadows only.

4. Create new material -> Materials Palette -> Choose or create new Category for material -> Create new default RedSDk material and Set him to the created Objects

5. Edit and add the material which you want use or need.

6. Add material Matte Shadow to the floor -> ( Category -> Miscellaneous )

7. Set default Rendering Type for:
   Hidden Line: Redsdk/Redsdk Hidden Line
   Draft: Redsdk/Redsdk Draft
   Quality: Redsdk/Raytrace Preview

8. Now you can try Render types and what we did set.
   Hidden Line: looks OK
   Draft: OK?! :) Yes OK but all Objects are black. This behavior is fine, because this type of render mode is preset without Global Illumination and it can not use white background as light.
   Quality: OK, here is the same problem as in Draft mode, but we can see reflections. Now we change rendering type from Ray Trace Preview to Global Illumination Standard and tadaaa -> light, light, light from every side :) and it is great because we not set any light source.

Note: Light comes from the Background of the Drawing. You can try change the Background Color -> Menu -> Options -> Background Color and select other color than white and you will see that light color will changed.

Tip: If you have mistakes on surface in this render mode, you need increase brightness color of Reflectance -> reflection color in material adjust to lighter.

Excellent tutorial!  I've been wanting to do a simple scene like this for a while.  And no lights required.  Thank you for sharing Majo!  I left the grid and coordinate system in mine on purpose.

One question.... I do not have the "Matte Shadow" option in my Miscellaneous folder.  Is that a new material you created or did it come with your version of TurboCAD?

Chachin..

Which version TC you use?

Please, try ...
Menu->Options->Materials->Load Materials and find propin.dat file and looking for "Matte Shadows" material.

And check it in folder C:\Program Files\IMSIDesign\(TurboCAD version)\Materials\RedSdk -> here should be file "misc_MatteShadow.red"

I'm using TurboCAD Pro Platinum 2015.

Attached below is a screen shot showing the materials loaded from my propin.dat file.  It matches all of yours except for the "Matte Shadows".  Oh well... do you think it can be created from scratch?

If it's simply a matter of upgrading to a newer TurboCAD, then that's ok because I am planning on upgrading to either 2019 or the following version later this year.

In the meantime I was able to recreate the floor and shadow effect using a box (instead of 3D mesh) as a floor and the same floor material used in this thread:

I'm using TurboCAD Pro Platinum 2015.

The .RED materials as "Matte Shadows and base Metals" are coming with TC2017 version.
As floor is possible use whatever material  ;)
