{ORIGNALFILENAME}. Or {*} is understood and maybe * is understood as well.

Yup it failed after a while so what template should I use so that the function automatically picks up each LAS file's filename and adds _dtm to it while saving its DTM raster to file?

There is nothing in {} I'm surprised it does not crash, fails or whatever. Anyway it won't work.

So now I am running opt_output_files(BC_LAS_List) = paste0("O:/LiDAR_Tree_Points/{}_dtm"). Idk if this is correct or not, but it is running, however I am noticing the memory use going up.

So I ran opt_output_files(BC_LAS_List) = paste0("O:/LiDAR_Tree_Points/{ORIGINALFILENAME}_dtm") thinking that the function will pickup the original filename from LAS file and put _dtm next to it to save the DTM raster file. But instead I got this error Error in eval(parse(text = text, keep.source = FALSE), envir) : object 'ORIGNALFILENAME' not found.

So I first ran pt_output_files(LAS_List) = paste0("O:/folder/filename_dtm") and then I ran dtm_tin = rasterize_terrain(BC_LAS_List, res = 1, algorithm = tin()). First thing I noticed was that the memory was still being used up. Also a little later I got this error: error occurred when processing the chunk 2. Try to load this chunk with: chunk <- readRDS("C:\Users\AppData\Local\Temp\RtmpeoYno9/chunk2.rds") las <- readLAS(chunk) [writeRaster] file exists. You can use overwrite=TRUE to overwrite it

Awesome, but I am still a bit confused, do I need to first run opt_output_files(LAS_list) <- paste0("folder/{*}_dtm") and then run rasterize_terrain which will automatically save the DTM raster to the disk path defined using opt_output_files?
