.....as in brick or tile shaders.I find they come in too large for the surface I'm applying them to.How do I resize them down?I've tried looking through my VTC Carrara 5 training vids but I'm having a problem with the player which just closes down.I've also looked  through Mike De La Flor's book but it gives me no clue as to how to do this.

Can anyone help me please.

You are stepping into a bit of a complicated area. There are (at least) two ways of dealing with this. You could dive into UV mapping to make sure your shader is not mapped over the whole object, but just per wall or something (I am thinking bricks).

Another solution, is to get one of the most important plug-ins made for Carrara: Shader Ops from DigitalCarversGuild. It has Programmable Scale, Size and UV Repeater components that will help you scaling your shaders.

Hope this helps!

This is one of the more complicated areas of the program.  The 3D program I came from had a lot less features but it was incredibly easy to manipulate location, rotation and size of texture and shader maps.  I'm still trying to figure out how to do this in Carrara.

So I don't have an answer for you but I sympathize. :-(

Hi **Incognitas can you send a print screen from this window so we can answer better to your question?

Not meaning to be rude but how will that help?
I'm just talking about resizing one of the very basic brick or tile shaders that are present in Carrara's content so they are smaller bricks or tiles?

Well then look at the prins screen from Discoseven, you will see the two fields with the value 4 X 4 look at your shade and grow this value, try 10X10
But you will need to look at color, bump and other values to adjust this...

Thank you that looks like what I need..

Again thank you..I may become less frustrated now.Well until the next time.

Hang in there Incognitas - keep pluggin away and have fun!

:)

After a bit of hassle, I decided that in a lot of cases, I got better results from using a simple texture map for the color and bump channels.  It gave me better detail and it was simple to size by using the tile seamlessly option.  I also get much finer control over the brick coloration, detail etc.  If I can remember how to insert am image here I will send up one you can look at that I designed for the new Hotel scene I am working on.

Still not coming right...Perhaps I should avoid anything with a regular pattern altogether and stick to the asymmetrical.

Nah- don't let the polys defeat you, incognitas. The uv's will map image/procedural area to polys so all you need to do is get a calculator and work out your poly/image area's height/width and calculate how many times you need to repeat your brick texture upwards and acrosswards to get a reasonable brick pattern. You might have to edit your original texture to make it work the way you want. If it's a procedural texture, try fiddling with the values in the offsets i.e don't tile 4x4, tile 20x7 or something.
Keep going!

Maybe you are trying to do something as in this tute?

If not, can you more clearly explain what is at fault with the attached screen shot please.

My Quicktime plugin isn't working properly in FF or IE so the video isn't working...Shame as Mark is an excellent teacher.

Anyway there is nothing wrong with the screenshot...but the bump map just won't oblige and fit to the pattern...I'm obviously doing something wrong as I get smaller tiles within the larger tiles but the bump map doesn't change to fit.It stays at the much larger size.

Can you post a print screen of your shader tree?

Incognitas
Have you downloaded a current version of the free Quicktime player.
That your player is not working is bad business!

Can you show the screen shot of the shader as in my first posted image --is it at all different?
Have you made a second adjustment somewhere in the shader tree other than those tiling numbers?

Well both issues are sorted.

I worked out where I went wrong and I had to uninstall Quicktime because it had become corrupted.Downloaded version 7 and everything seems ok.

I have to say that whatever the software that the the material/shaders side,although fun,does seem to have a steep learning curve.

Shaders /rendering seems to have an almost continuous learning curve.
The Carrara shader tree and the things that can be done, is about the most logical and most easily "learnt" that I have seen.

Make a point of opening the many types of shaders in the browser. Analyse how they are put together. Play with the adjustments.
