Dynamic paint - not rendering

respected artists…

can any one help me to find out the reason for the following issue:

I had made a mesh - canvas for dynamic paint - waves
and another mesh a brush to effect the canvas.

I had subdivided the canvas sufficiently and it is also having displacement modifier in it
while animating the scene by ALT + A, in the view port I’m seeing the result I desired but while rendering, (actually I had even baked the current chache before rendering) all the frames are alike, with out any effect of the dynamic paint

If I open a new blend file and create new mesh, then it’s working for the new mesh

I don’t know what went wrong…

Please help me…

Without the blend hard to know… But whenever something looks fine in viewport but the render is different, it’s often a modifier issue. Very common one is subsurf preview of 1 and render of 2. Basically check all your modifiers on all objects and make sure if there is a modifier that has options for viewport and render that they are both the same – in general change the render to match the viewport. Another gotcha can be modifier visibility (the eyeball icon) make sure render (the camera icon) matches.

If it’s not post a simplifed version of your blend.

Also modifier stacking order is important. Try moving dynamic paint to the beginning or end of the stack.

Yes, that absolutely should be included in your troubleshooting checklist :

Change the dynamic paint stack order, free bake, re-bake, render, repeat.

thanks for the kind response

I’ll surely check it out and update the result

thank you once again…

yes!
it worked

I had a displacement modifier below the dynamic paint
I tried the order of displacement modifier above the dynamic paint and then it worked

Thank you sirs…
