Hello Laurie,

 

You can do that using the Height-field By Colors Tool, first you have to paint this image and after that assign a height for each color, here you can find a video explaining how to use this tool.

 

If you have any doubt or problem don't hesitate to post it.

Best Regards.

Hi Pat

I've beem trying but it aint easy.... I might be getting the photoshoped image wrong because when I start height field by colour I still get the "More than 50 colour" warning and I cant face going through them all to set values.

I'll try and re-do the photoshop image and have another go.

Hello Pat

 

RhinoGold HeightByColor works by assigning a height to a specific color, your image is a photo with millions of colors, furthermore the colors (gradient are very similar) it has a hard manually work to reduce the colors, but is possible make an color map from you picture.

First you have to set the areas which you want to assign height with a specific colors I used a grayScale and only five colors, select the zones that you want with a specific height and paint them with a color, each color will have a different height.

This is just a draft

As I said you your image is a picture, with a lot and very similar colors, so you have to be patient and paint every area (hair, swords..) to get a good color map.

 

I hope help you, and if can help you in anything just tell me it.

 

Best Regards.

here's a example two colors white and red when I open says more than 50 colors...I don't have photo shop..and I don't really feel like 'painting' ....the rhino video shows a example with several colors (I think it was a clown image) working fine but I always get the same thing 'over 50 colors' so I can't use heightfield by colors yet.....

See Pat this is a zoomed image of your sample showing pixels in somany colors I think this is the reason

it shows that many colors, the best way to work in HeightByColor is from a victor design converted to image.

Hello,

Tariq is right, it seem like this Picture only has red and white color, but in fact it's a red to white gradient scale like Tariq showed in the zoomed picture,  Between red and white there are a lot of colors, so you have to paint this image just in red and white or any other color, and then just then, open with HeightFieldByColors, because only then will be a valid and usefull colorMap, otherwise you would'have too much colors to work correctly, 

Look the difference between the two pictures:

Left Picture (yours) have a lot of colors between white and red (not good to use).

Right Picture (Mine) it's your Image repainted by areas only have 2 colors, Red and White.

So, as you can  see in this kind of pictures (treated pictures), HightField by Colors only detect 2 colors instead more than 50 like the first picture, and you just have to assign the height to each Color

I hope It helps you, if you have any doubt just post it and  I'll try to help you.

Best Regards.

Hi Pat

I've had a go again and converted my picture to grey scale, it worked up to a point.

I had about ten shades of grey to play with which was ok but the result I'm getting is to sharp, not really the "coin"

type relief I was looking for. I'll keep at it and let you know how I get on.
