wood grains

[sakar_deepak]

Hi friends

I am struggling with this problem for long. Attached is one rendering at 'Medium' quality of Teak Wood. My problem is that ( i have tried all settings i knew ) it does not show the wood grains at all in rendered pic. It does not show the wood grains as is shown in 2nd attached pic. 

And, the problem is not with just Teak Wood, it is with all Wood materials available in Revit library. 

What is wrong ? Please tell me.

Did you setup the material, duplicate the Appearance asset, and add the image you want?  By the way, the image you posted is not a good one to use in a material, it will tile badly as shown in my test below.  I suggest you use one of the OOTB Teak wood appearance assets instead.  There is a reason they don't show the grain too much and top strong is to avoid the ill tiling effect.

Hi @sakar_deepak

The wood grain feature is under the relief pattern in your appearance tab. You can add an image of a wood grain or select wood from the drop down menu.

You can vary the amount of grain according to your model. Amount is the Relative depth of the wood grain, when Bump is based on wood grain. Enter 0 for a flat surface, a positive number (between 0 and 10) to raise the grain, or a negative number (between 0 and –10) to reverse the grain.

As @ToanDN mentioned the quality of image you use and the image resolution matters. Please test your render with the wood grain image attached and let us know.

The attached screen cast will put my problem clearly. I created one Teak wood material from library. Rendering does not show the grains as shown in the Material Image as displayed.

@Viveka_CD Thanks for the reply madam. I have three queries.

1. Why didn't you choose relief pattern " based on wood grain" , why did you choose " custom " ? 

2. If we have already chosen an image for a material, why do we need to choose an image again for relief pattern ? 

3. Why did you choose a different image for relief pattern ?

Hi @sakar_deepak

Thank you for appreciating our forum responses. Yes we do have members, expert elites and new visitors who sure make our community interesting and are always glad to help!  

To answer your questions:

Enabling the custom option has a feature to play with the 'grain thickness' - see image below. In certain interior views these settings/additional image for grain enhances the material appearance (looks like wood) rather than just plain brown color.

Again this depends on your model size and render view settings.

From your screen-cast, it looks like you have to select the custom option from the relief pattern settings as shown below.You can adjust attributes like noise etc.

1. Relief pattern based on Wood Grain only works if you choose procedural Wood for texture, not if you use an Image for texture.

2. If you use an image for texture, you need to use Custom for Relief pattern because the texture Image does not have any "grain", only colors.  Under Custom, you can pick any image to create the relief pattern.  Normally, a black and white or gray scale image provide better result than colored images.

3. You can pick the same image used for texture to be the relief pattern image.  But as I said above, a monotone image provides better result.

@ToanDN Thanks Sir,

1. But Revit does not provide monotone images for relief/ bump patterns. Where do we get monotone images from ? 

2. Earlier you mentioned OOTP, what is that ?

[ToanDN]

They do provide some for the more common patterns such as tiles and bricks. For wood, you can save the color texture image to monotone to create a copy for the relief pattern. To be honest, it's not worth it to do it for wood materials because the effect is minimum due to the size of the grain. Or you can use what Viveka suggested, using the procedure wood relief pattern instead of an image.

OOTB is out of the box, meaning stuff shipped with the program.

Hi @sakar_deepak

Thanks for sharing the video.

Hope your issue is resolved and we will be glad to take a look at your final render.

Let us know if you have any additional questions!

[sakar_deepak]

@Viveka_CD I am glad to show you my rendering. Though the Teak wood texture is not as good as desired, the rendering is final for the time being. Hope I will be able to produce better wood texture next time. 

Your comments on rendering are most welcome and desirable. Attached is one rendering.

Hi @sakar_deepak

Thank you for sharing your rendering with us. The model is neat and it's a great start!  

A few suggestions to improve the quality of the image:

• For improving the teak texture, I suggest isolating a part of the teak shelving and doing a render region.Saves times and you can test the settings in a small region to save time and improve quality for the whole image.
• Try changing the resolution of the rendering for better quality. More information HERE
• Lighting in you rendering can be fine tuned for better results. Some best practices on lighting HERE
• I observed that some of your grey dome lights do not have a light source in the light fixture.
• Some of your ceiling lights are bright and requires dimming.
• Turn off lights not required for that view. More tips on controlling lighting in rendered images HERE
• Try changing your settings to production quality.See Image below:

Try modifying your scene to object settings.See image below.

Let us know if you have additional questions, and you are welcome to share your methods tried and tested during the process.Do send us the image as you progress on the rendering.

Good luck!
