Materials Textures

When applying wood materials to my 3d drawing, the material just appears as a solid color.  There is no graining (finish, texture) as I would expect with a wood or stone material.  I am using the Realistic Visual style, and have the Materials display setting on materials and textures.  What am I missing?

Hi,

 

most usual for that situations is the fact, that units set to the drawing do not match to your geometry size.

Make sure that the setting in -DWGUNITS is correct.

 

If not then upload a drawing with one of your wooden objects so we can take a look into it.
If you defined your own material with mapping images then please use command _ETRANSMIT to make sure we get all the data.

Thank you Alfred for responding so promptly.  I will check these settings later and give you an update.

 

Thanks!!

My DWGUNITS variable is currently set at 1.   How do i know if this is "correct"?

Hi,

 

>> My DWGUNITS variable is currently set at 1

When you start the command you get that list:

And when you have selected 1, then your calcluations for rendering are based on Inch.

Yes.  Okay. My units are set at inches, which is my preference.  But I do not understand the relationship between using inches and not being able to get material finishes and textures.  I will attempt to upload a file in which i have having issues with.

 

Thanks for your time.

Hi,

 

when you start _RENDER do you see that message:

This message shows me that you have not run the -DWGUNITS command to the end (where it asks to match INSUNITS with these current set units).

But that was only the start of a bit longer way to go.

 

Next is the size of the mapping, I take the material "Cherry(2)" as sample, you might have to correct more than just this one material:

Looking to the image definition there is a texture mapping defined based on an image, that image is defined to be 1x1 (which means the mapped image with your units = 1inch x 1inch in size). Take that image and place it 200 times onto the table ... you won's see any structure of the image, it's much too small!

Next is the lightning: you have not placed a manual light, but turned on the sun-light (which makes all much to light).

Turn the sun-light off, this brings you back to a default lightning and ... look to that result:

 

In AutoCAD model-space:

That's the point to start now with a closed scene (no light-rays can exit a closed scene), with light (inside stay with point or spotlights, outside you can use sun and sky)

 

HTH, - alfred -

You definitely made it look at intended.  However, I cannot find the editor settings that you showed me. All I can find is what is attached in attached screen shot.

Hi,

 

>> I cannot find the editor settings that you showed me

Because you are not working with the material I have shown.

 

You have to differentiate between textures build on images (like I have shown in my screenshot) and procedural textures (as you have shown in your screenshot).

For images you have to modify the tile-size to define how big an image is when it is projected onto the 3D-geometry.

For procedural textures you have to find out which parameter in the calculation makes the size ... and that parameters need to be modified (like noise and grain in your sample).
