3D shape with rough surface - illusration help

[venu_vt]

Hi all,

I am using affinity designer nowadays a lot for scientific illustrations. Usually, I figure out how to do it in affinity if I see an illustration but I am unable to figure out how to do the following.

Basically creating a rough surface on a shape as the attached image. I tried playing with 'noise', but it's not giving the same effect.

Any help on breaking down the process is really appreciated.

Thank you!

If each microbe is a shape, using a bitmap would likely give the best result.

There are multiple ways of adding a bitmap to a shape from simple clipping where you place an image on top of the shape on the screen and in the layers panel drag the bitmap onto the shape after suitable scale and rotation etc which  will clip the bitmap to the shape.

Alternatively you can apply a bitmap fill using the gradient tool, look to the context bar options.

Finally you could probably use the effects studio to add an inner glow to each microbe.

Clipping as Paul suggested. Added the file too, so you can see how it was done.

Hi @Paul Mudditt and @DM1

Thanks for the hints. This is really helpful. 

I was also thinking if we can create that ridge surface effect without using an image? For example bursh/combination bursh suggestions?

Thanks a lot for the help. Stay safe!

Sure, draw your vector shape, then in pixel persona paint with whatever brush you like and a pixel layer will be created automatically clipped to the vector shape, quick example here.

Hi @Paul Mudditt,

Thanks for the direction, I will play around with brushes and effects.
