Help needed adding ores to worldpainter map

Hi folk. My son has created a world using World Painter. We want to add in the IC2 ores to it, but have hit a stumbling block. World Painter tells us that the highest block id it uses is 4095. However a test run reveals to us that the ores from IC2 are using block 4149/1 /2 /3 & /4 (info gathered using F3 + H in minecraft). Can someone help me in figuring out how to get the ores into World Painter please? I have tried their support but they have referred me to here as it looks as if IC2 is remapping the blocks somehow. We have tried using the ids given on this website (which are in the 400s) but all that shows in a test run after using the data in WP is the chequred block instead of the ores themselves.
The only other mods in use are:-

Building bricks
Simple covers
hopper ducts
villagebox
lunatarius core
Bd - Lib (linked to building bricks)
MC multipart
schematic (only on single player)
JEI

This is using Minecraft 1.10.2

Thanks in advance for any help you can offer.

thanks for the reply. Just to check to see if I have this right. Instead of using the block id of 4149/1 I should use instead minecraft:copper_ore? (Assuming that Worldpainter can use that format).

Just checked with worldpainter and it cannot use the registry names. So I'm hoping there is another way I can remap the block ids to with in the 4095 limit.

Thanks for the correction. But as noted above Worldpainter cannot use the registry names.

I shall have to try goet hold of the author of Worldpainter and see what he/she can do. Thanks folk

I don't suppose any can shed any further light on this as I'm not getting anything back from WorldPainter?
