Does anyone know how to use displacement maps without the renders creating giant spikes?
Many thanks

Use min/max displacement level in material's settings. Hope it helps. :)

Already tried that Maru... put displacement to 1% and it still spikes. Am I doing something wrong?
Bump and normal maps work well though.

First, chech your displacement map. If it only has black and white values, it is normal behaviour. Dome gray values (like a gradient) will smooth it out.
Secondly, maybe you need to subdivide your mesh into smaller pieces, could be helpfull.

Displacement in Corona has units relative to your scene units.
You can assign a defined displacement height in mts cms or whatever unit u use in apropiate material tab (Min Max values as maru said).
It helps a lot if you can put an image of your displacement map or material settings so we can help you better.

Where did you change that value? I don't remember any percentage-driven setting for displacement. What version are you using?

I have converted all my Vray mats to Corona by use of DeathClowns script. Too me forever. But when I use Displacement it goes really spikey and Corona struggles to render.
I have eclosed a dis map of a brick wall that spikes.
Also, when you download objects from the net they are always Vray ready. They sometimes have maps of "folds" on sofas or ambient occlusion maps. I cannot get these to work. I tried dragging them onto object or converting them. Does'nt work.
I have included a div map that I don't konow how to apply.

I change from 100 to 1 in the Compact Map rollout.

This is the one you are after. Put a max level as expected according your own scene units that makes sense.

Wow! Great. I was changing the wrong dial. I was using the map roll out.... did'nt know I use it as you instructed.
Many thanks for your answer :)
