I tried to import alembic files from Houdini using the geometry cache option. I successfully imported the alembic file with single one frame, but it resulted in crashes when I imported the alembic file by a specific number of frames [001-120]. Here are my alembic files: Single One Frame: [https://ucsb.box.com/s/3oxwa9gek7j0uo6jqw1pgo5i7wtgwcue](https://ucsb.box.com/s/3oxwa9gek7j0uo6jqw1pgo5i7wtgwcue) Frame [001-120]: [https://ucsb.box.com/s/at6hnu23a0zc7mwsdotc44cx1jj49h85](https://ucsb.box.com/s/at6hnu23a0zc7mwsdotc44cx1jj49h85) ---

Hey hanwei, Thanks for reporting this. I only got a crash because I ran out of memory. The editor jumped up to 45GB memory usage. I’m not sure exactly what’s happening, but I’ve entered [UE-43737](https://issues.unrealengine.com/issue/UE-43737). You can track the report’s status as the issue is reviewed by our development staff. Please be aware that this issue may not be prioritized or fixed soon. ---

Hello Williams, are there any news on this bug? Could you share some outlook for the future of the experimental alembic importer, will it get more love? Best Regards ---

Hey , Currently this is still unresolved. It was noted that this might be expected with larger files, but 45GB is still a bit ridiculous. It’s been moved to another ticket UEAP-177 which includes a few other general improvements on Alembic Imports. Sorry that’s not very informative, but it’s on the to-do list. ---

45GB isnt all that ridiculous for an alembic, they often get to be quite large. Also experiencing crashes over a certain size threshold which is disappointing, although I’m yet to test if theres any compression that can be done to keep UE memory from imploding ---
